Slowly run 2x to 3x your container size of plain pH’d water to really flush it out. This means that when the coco has lost 10% of the water that it can hold you should water again. My combo meter uses a .700 conversion rate. Managing the Electrical Conductivity (EC) of the water that is available to the plants is a key practice to maximize the speed of growth and yield of the harvest. Yess finally buds are on there way. Copyright © 2020 Coco For Cannabis Inc All Rights Reserved, Growing Cannabis in Coco Coir with High Frequency Fertigation, Understanding EC, PPM & TDS for Growing Cannabis, How to Manage Cannabis Fertigation by Measuring Run-off EC/PPM, How to Water Cannabis Plants in Coco Coir. is it normal for coca to have such a high run off or did i mess up by not flooding my coca until the water ran clear. Lately, we’ve had many novice growers ask us to explain PPM, TDS and EC readers, and how they all work together to help you grow better cannabis. great post! We welcome all growers who want to learn, share and grow together! I figure the soil is much more flexible but would still have an … However, if it is not possible, you may need to lower the inflow EC so that the natural rise in EC does not cause damage to your plants. But you have another dimension to coco in that normal interval feedings of F/W/F/W can be changed to something like F/F/F/W. By Volume of Water Needed: Coco mixed with perlite has the ideal air to water ratio when it is 90%-100% saturated. If you’ve ever flushed a crop at the end with straight water, you would know why. I suggest you flush with 1/4 strength nutes instead of that clearing agent. By the end of 6 gal runoff is near ppm of what i put in (300ppm). The founder of I Love Growing Marijuana, Robert Bergman, is a marijuana growing expert … When considering the target EC for your nutrient solution (inflow), you need to understand that the EC will rise between fertigation events. What should my runoff ppm be in soil? Nutrient companies should provide you with both a set of recipes in a feed chart and a set of EC or PPM ranges for each stage of growth. You definitely want a pH between 5.8 – 6.3 (Lower for hydro, higher for soil). Grow Your Own, But Don't Grow Alone... Let's Grow Together! Around 400. You can convert back later if needed. Inflow is added at the bottom of the range and run-off is kept from exceeding the top. I'm experimenting with both. Log in or sign up to leave a comment Log In Sign Up. Clearly, cannabis plants enjoy increased parts per million as they grow. The run-off EC is the best proxy for the EC of the nutrient solution in the coco. The cyco kleanse may be fine but I have no experience with it. When calculating your target inflow EC, you need to start with the low end of the recommended range. ). So from now on I feed my base nutrients at full strength (4mL per liter) and use my other nutes at 1/4 to 1/2 depending on how they look. Realize: Plants may be burned by abrupt changes, but they may be able to adjust to the new higher levels. Santos L Halper Member. PPM (Parts per Million) levels is the measure of nutrients in the water used to feed your cannabis plants. No just water, its suppose to clear salt build up and they suggest using it once a week. Source: Just 4 Growers: Global Garden Community The "EC-to-TDS Conversion Factor: NaCl (avg. PH is a concern though, unless you're running coco it sounds like you're a little low. Both heat and low humidity also cause increased evaporation. Budsmoker187 Registered User. Be sure to read our tutorial, "EC/PPM Targets for Fertigating Cannabis"The doses for the base nutrients (Flora Micro, Flora Gro, and Flora Bloom) are about half the dose that General Hydroponics recommends in their feed chart. Your plants know better than anyone what EC they prefer. If you are growing a strain that likes “high nutes” then you may increase the inflow target, and work with a higher range. My head hurts from reading so much about pH, PPM and EC. Im using coco mixed with perlite for my grow atm, they are in week 3 of flower, however i noticed that my runoff ppm is way lower than it should be. I’ve really fucked up my pH! While we try to make cannabis growing as simple as possible, some technical terminology is just unavoidable. share. Do you put that kleanse stuff in the nutrient solution or do you just mix it with water by itself? Was told to not even start Nutes until week 6, wanted to know what I want my feeding schedule and PPM. Additionally, a 50/50 blend of coco fiber and Vermiculite is excellent for rooting cuttings and helping seedlings get off to a promising start, as Vermiculite clings to moisture, nutrients and a little air at levels that can be beneficial to young plants. Be patient if minor burn shows as you increase EC. For example: let’s say there are 3 lbs of cannabis compared to 1,000,000 lbs of water, we would say the concentration of cannabis is 3 ppm. But … It is a great way to share your experience and ask questions along the way. For example, if the EC of the starting water is 150, then your EC target for the nutrient solution (inflow) can be adjusted by +150 points. Therefore, in addition to lowering inflow EC, you should also increase fertigation frequency. i like reading posts from SCMC as he definitly knows what he's talking about. Started grow in Coco only and using RO water and organic nutrients. And if your ppm is 500: 500*2/1000= 1 EC . Just as the nutrition needs of a plant change during its life cycle, its optimal EC range also changes: starting low, reaching a peak during late bloom, and going down sharply at the end. You probably want a PPM around 600. The EC that matters is the EC of the nutrient solution suspended in the coco at the root zone. If the starting water already has a high EC, you should adjust your target to account for the EC of the starting water. You need to start by setting a target inflow EC value, but your real goal is keeping the run-off value from exceeding the maximum. who ever says runoff #s with coco mean nothing knows nothing about growing with coco. I grow in coco so I can see how they react within a day or 2 normally. This now leads me to my true question. You shouldn't worry about run off ppm, that's just a combination of the ppm you put in and the extra salts you flush out of the soil. The first test we ran 500 ppm and 5.9 ph through the coco. The Science and Practice of Growing Cannabis. As water transpires from plants and evaporates from pots it causes EC of the remaining nutrient solution to increase. This is the PH buffer. We explain the importance of EC in “Growing Cannabis in Coco Coir with High Frequency Fertigation” and “Understanding EC, PPM & TDS for Growing Cannabis”. If you’ve really fucked things up with the pH in your coco substrate you may need to take more decisive action. However if you get a PPM of 600 and a pH of 5.3 you are on the borderline of poisoning the plant. I've been doing a cal mag foliar spray twice a day and I'm already at 500 ppm of only mega crop in the fertigating water. Since I started checking my run off and upping my nutes I noticed my run off ppm has been lower but my ph is still higher. What should your coco run off be? Is it better to use an EC or a TDS meter? Start with the LOW end of the Recommended EC/PPM Range. To determine the correct adjustment for your particular grow, use the following process: You may or may not be able to use untreated tap or well water to mix your nutrients. my plants are 16 days old and I'm using canna coco with 10% perlite canna a+b 1/4 strength. Coco nutes should be here Friday. On top of that, the physical appearance of coco coir isn’t necessarily a reliable gauge for knowing when the medium needs more water. Lowering the EC makes it easier for plants to pull in all the water that they need. 100% Upvoted. If so, that could be a problem. But how can you determine the dryness of your coco coir? Thanks for that. Heat and low humidity increase the rate that plants draw in water through their roots. Depending on your plant’s maturation and the number of nutrients it can absorb, the ppm should range from 750 ppm to 1500 ppm. I've been pinching them out and lollipoping they now been in flower for 2 weeks. My tap water is `120 ppm, out of the faucet. Your main management goal is keeping the run-off value close to your run-off target. If there are any signs of burn, and the run-off is not significantly higher than inflow, then your target EC range may be too high. Lightly wet the coco medium (too damp won’t encourage root growth). In particular, you should avoid nutrient lines that recommend high EC ranges and frequent flushing. If you are starting with low EC water, the bulk of the EC will come from the base nutrients. Water that starts with an EC of more than 300 should not be used. In order to manage EC, you need to set EC targets for the nutrient solution that will be available to the plant. If EC or PPM ranges are not provided, you should use the general ranges recommended above. Regardless you should only add nutrients if your ppm level's get low, and only then if you are experienced and you ladies show signs of deficiencies that only fertilizer can solve. Always 1/4 strength nutes or some sort of a tea with nutrients for a flush. The key consideration is the EC. Could someone PLEASE help me understand. I also did a flush today with the same results. There are minerals in the tap water you will use to water your plants and you will be adding some fertilizer solutions to the water which also can be measured in parts per million. If you are growing a plant that prefers lower nutrition, then you may want to lower the target and maintain EC in a lower range. For example: let’s say there are 3 lbs of cannabis “diluted” in 999,997 lbs of water (for a total of 1 million even), we would say the concentration of cannabis is 3 PPM for those given weights. Attached a pic cheers. It's hard to tell with the yellow HPS light but your leaves looked striped. PPM is Higher in your Runoff than Sump. Beyond the supplier’s recommendations there are several variables that you should consider to fine tune your EC target. I water with nutes every other day. If EC or PPM ranges are not provided, you should use the general ranges recommended above. Can you take a closer pic of the leaves? Coco coir retains water well — too well, if you’re a cannabis grower who tends to overwater. If you ppm starts getting to high and your ph is dropping to low, it's time for a heavy irrigation of 1/4 strength solution to 'flush' your media of the accumulated salts. Ohh seriously? I grow in coco so I can see how they react within a day or 2 normally. I feed at 5.8 and the run off has been 6.5 give or take a point. So if I want a ppm of 720, I set it at 840, ... Lucas stresses that you should always use FULL STRENGTH nutes. Sounds like I've been running my PPM way too low. Slow the increase and allow plants to adjust. hi growers. Since water is about half the total volume of saturated coco, the amount of water required should be about 5% of the container volume. So from now on I feed my base nutrients at full strength (4mL per liter) and use my other nutes at 1/4 to 1/2 depending on how they look. PPM stands for “parts per million” and is a unit of concentration. It seems that Greenleaf Nutrients Mega Crop has enough of both and if you’re having calmag deficiencies, you can just raise your dosage of MC (GRADUALLY) instead of … We have a wonderful community of growers and you are welcome to join! hide. I am currently in my 4th week of flower and I think I may be seeing signs of potassium deficiency. Starting water must be lower than EC 300. If your withing 200ppm + or - and your ph is between 5 to 6.3ish you should be golden. If you have plant nutrient recommendations in EC units, an EC meter is convenient. However, tap and well water may be used if they start less than EC 300. I used to but apparently im supposed to use nutes constantly in coco, i do a flush once a week though with a salt clearing agent. PPM stands for “parts per million” and is a unit of concentration. The Science and Practice of Growing Cannabis. Check with the breeder or do research on your strain. Why do you suggest quater strength instead? Start increasing your PPM by 100-150 until you reach a spot that is best. Ph is within range. Every working meter should get a reading of EC 1.0 from this solution . This should be rare, and it might indicate some sort of salt buildup at the root zone. And do you ever use plain water? Water ppm readings have applications for both hydroponic and conventional soil cultivation methods. If you get a mix that has an 800 PPM and a pH of 6.0, that is fine. Plants that size should be fed and least twice a day to at least 20% run off each time. One thing I do is keep a separate bucket of water at 6.0ph, when my reservoir levels drop I just top it off with this water. At this point you are ready to determine your EC range targets for each stage of growth. If you are looking for advice and support throughout your grow, we encourage you to start a Grow Journal in our Grower's Forum. My tap water is PH 7.5 reading 199PPM. Not sure how much cal mag I should add to the fertigating water. See our tutorial “How to Manage Cannabis Fertigation by Measuring Run-off EC/PPM”. I'm going to add more bloom nutes next run. If the runoff is higher than 1,200, like 1,500 ppm, then the plant is not uptaking what you are putting in and is just wasted. The max ph range you’d want would be 5.5 to 6.5, growing pot in coco outside of that pH range will cause nutrient problems. Growers should avoid using coco-specific nutrients when amending coco with Perlite to keep plants from yellowing and under-performing. Use gentle lighting at 24 or 18 hours per day, and if cloning use a humidity dome to allow your young marijuana clones to take in water from the air until their roots form: The ideal pH for coco coir cannabis grows is between 5.8 and 6.0 in the vegetation stage. Ph should be 5.8 – 6.0. I wouldn't worry about the ppm's but the pH is a problem. You need to be able to measure the EC of the run-off from each plant. I grow in 3 gal pots of coco. I've been feeding them PH 5.8 tap water … You want to "balance" your soil, that means what goes in should … If you use tap water, your reading should … I read somewhere else the ppms are low because the nutes are being used up? Lower inflow EC until you can maintain run-off EC in the appropriate range. My girls sprung back to life. My solution going in is around 750ppm, but im using cyco so apparently that's equivalent to 1100 or so ppm. The increased water that is taken up by the plant and the increased evaporation causes the EC to rise between fertigation events. 0.5) " from my meter shows that it is part of the "Hanna" group in the PPM conversion chart or what many just call a "500 scale" meter. For this reason, your main task is maintaining the run-off EC within the acceptable range. Ph is also coming out around 6.9-7.0. My tap water comes out at about 140 PPM and when I'm done adding nutes as per the GWE schedule it's usually around 400 PPM. Discussion in 'First Time Marijuana Growers' started by ElChoppo, Jul 20, 2018. We also have a live chat room, which is a great place to ask questions, get quick answers, and chat with fellow growers. It is set for the standard EC targets, with no grow specific adjustments. 2. 750ppm in yet 4000 ish coming out. We ran a test with the Pioneer Coco from Batch 64 to see if we could lower the ph and ppm (ECx500) of the water coming out of the coco. ... but now I have changed to coco tec as it's easier to order and works good just been adding the … Advice/Help. I realize there are variables but looking for a basic explanation of how things “should be”. As I discuss in more detail below, you are always working to maintain EC within about a 300-point range. Running autoflowers, medium Happy Frog soil, fox farm nutrient trio and call mag. Make any changes slowly and always verify that your plants approve of the change. You should also be using a ppm meter to measure total dissolved solids while you’re measuring the pH. Once you determine your target inflow EC and are maintaining the EC in your coco within 300 points, make sure that your plants are happy! Listen to your plants! This buildup persists for a while, and then slowly dissolves back into the runoff, resulting in a higher PPM. But i get nute burn if i increase anymore so am i fine then? Different strains have different nutritional needs. However, you can only measure the EC of the inflow and the run-off. However, if the supplier recommends EC ranges that are significantly higher than these general EC ranges, I would recommend finding a different supplier. Check out our Product and Equipment Guide for our Recommended Grow Lights, Grow Set-up Equipment, DIY Projects, Germination Supplies, Plant Training Supplies and everything else you will need during the grow! Using distilled water or water filtered through reverse osmosis is best. Do not adjust the target more than +300 points. I am soooo confused and have never had this problem before.. i am in my last stages of veg and I decided to check my runoff it was anywhere between 2000 too 3000 Ppm and ph was coming out at 6. During the flower stage, optimum parts per million rises to 1000-1100. If you rinse your coco coir more than three times and it’s still showing 450 or more ppm, and/or the pH is out of range, do not use that coco coir. To get an EC value, multiply the ppm reading by 2 and divide by 1000. Starting with good quality (low EC) water is assumed. You should start by checking run-off daily until the numbers become predictable to you, at which point, you can skip days. 400 microsiemens = 0.4 millisiemens. However, natural PPM is 350 out of the tap. whats up dudes? The PPM hardness of your base water determines the PH of the medium runoff. Help! save. © Copyright 1999 - 2020 Grasscity.com is a part of, (You must log in or sign up to post here. Convert all values to microsiemens of EC (values in the hundreds and thousands). im within a WEEK of starting my first hydro grow (WOO HOO!! ) Checking with the breeder information is best, but as a general rule: Always “listen” to your plants! If you are using reverse osmosis water, the reading will be 0 to 10 ppm as it is completely free of minerals. report. Discussion in 'Coco Coir' started by Budsmoker187, Dec 15, 2010. 2 comments. Tonight runoff came out around 1150. Never let a plant go more than a few days without testing her run-off EC. As described above, water is removed through transpiration and evaporation faster than salts are removed. What ppm and ec values are people running thru Coco thru seedlings, veg n bloom. However- the ppm it displays could be 500, 640, or 700- depending on the tester used. I have just purchased a PPM meter and wanted to know what PPM I should be using? If the parts per million reading is higher than 450 ppm, and/or the pH is wildly out of range, repeat the experiment to see if you can get runoff water that’s less than 450 ppm and within pH range. If you are unable to fertigate frequently, then it will be harder to maintain a tight range between inflow and run-off EC values. I'm on day 21 and plants are looking great. My nutrient feed chart for the General Hydroponics Flora Series nutrients is provided. The general ranges provided above are appropriate for General Hydroponics Flora Series. I hope this issue works itself out. i check my runoff #s (ph/ppm) every single time i water/feed. That's the only reason I suggested the 1/4 strength nutes for flushing. Coco specific nutrients do this very well.. they also need to be stronger, there should be no difference in Drain to Waste and Recirculating feed charts, coco consumes the nutrients the same way regardless of the setup. Thus, if your EC is 1: 1*1000/2= 500 ppm. RO water works perfectly in bringing this down as low as needed with simple additions, so my question is, what is the ideal PPM for a coco and soil grow both? Coco specific nutrients do this very well.. they also need to be stronger, there should be no difference in Drain to Waste and Recirculating feed charts, coco consumes the nutrients the same way regardless of the setup. Add and subtract EC for each of the 5 variables below based on the particulars of your grow. How often do you feed? *EC units are expressed in microsiemens. So I flush with 300ppm 6 gal of solution per plant, checking ppm run off at 2 gal, 4 gal, and 6 gal. When considering the target EC for your nutrient solution (inflow), you need to understand that the EC will rise between fertigation events. The only reason that I suggest 1/4 strength nutes is because I know there is no risk to the plants. I found feeding lower PPM (in strain specific cases) that i was having more deficiencies . Always so they been veg for a few weeks since and seem all ok now. Coco coir should be watered when it’s 50–70 percent dry. With soil cultivation, the water ppm should be checked after adding additives to the watering vessel. My runoff ppm is almost double what I'm putting so should I give a plain/calmag watering? I only put very min amounts of nutrients and always water in between.. they were definitely in lockout and I needed to remove the salts so I used florakleen and flushed through. This is the PH buffer. The PPM hardness of your base water determines the PH of the medium runoff. If however the runoff starts off low or at 1,200 ppm you can take your nutrient load up a bit. But yeah its the cyco kleanse not sure if youve heard of it but its mainly just citric acid and dextrose. What's your ratio of liquid cal-mag to mega crop? so i have tried to google my questions but not many clear answers. keep flushing until your run off ppms are very close to input ppms. Remember that the run-off EC is the value that you need to control. Long story short, check your run-off at least once a week to make sure your within range. Let's say you have a solution with an EC of 1.0. I had no idea, ill try doing twice a day when the lights come on and see how it affects ph and ppm. My ph going in is also at 5.5. I know there’s a lot of debate regarding CalMag in coco, and if it should be added with every feeding or even at all. Therefore, the target for the EC of the inflow is always lower than the maximum acceptable run-off score. I'm 12 days from sprout and the leaves on the 2nd node are looking pretty wavy. High frequency fertigation is the best practice. We used a 1 gallon pot of coco for each test. It happens fast. Do you have a closer pic of the leaves. What should my PPM be? This causes the EC of the nutrient solution suspended in the coco to rise between fertigation events. The lower the initial EC the better. Ppm going in is 750. COCO ph and PPM questions. The best ph for flowering is between 6.0 to 6.2. PPM Levels for Cannabis Plants. In the chart below, you can find general guidelines for optimal EC at different life stages, however, there are differences between different nutrient lines. Never use plain water in coco until the flush. Therefore, you should start with the recommendations from your supplier. Calculate your total adjustment, but if the total you calculate is more than +300, limit your actual adjustment to that.
