what should my ppm be in coco

Discussion in 'Coco Coir' started by Budsmoker187, Dec 15, 2010. 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. 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. The PPM hardness of your base water determines the PH of the medium runoff. I wouldn't worry about the ppm's but the pH is a problem. 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. When calculating your target inflow EC, you need to start with the low end of the recommended range. Santos L Halper Member. Tonight runoff came out around 1150. Different strains have different nutritional needs. If the starting water already has a high EC, you should adjust your target to account for the EC of the starting water. 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. The PPM hardness of your base water determines the PH of the medium runoff. Beyond the supplier’s recommendations there are several variables that you should consider to fine tune your EC target. If your withing 200ppm + or - and your ph is between 5 to 6.3ish you should be golden. If EC or PPM ranges are not provided, you should use the general ranges recommended above. Therefore, in addition to lowering inflow EC, you should also increase fertigation frequency. We also have a live chat room, which is a great place to ask questions, get quick answers, and chat with fellow growers. With soil cultivation, the water ppm should be checked after adding additives to the watering vessel. Water that starts with an EC of more than 300 should not be used. report. How often do you feed? ). Growers should avoid using coco-specific nutrients when amending coco with Perlite to keep plants from yellowing and under-performing. The first test we ran 500 ppm and 5.9 ph through the coco. 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! Slowly run 2x to 3x your container size of plain pH’d water to really flush it out. I've been pinching them out and lollipoping they now been in flower for 2 weeks. Therefore, you should start with the recommendations from your supplier. And do you ever use plain water? Therefore, the target for the EC of the inflow is always lower than the maximum acceptable run-off score. 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. 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. 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. So if I want a ppm of 720, I set it at 840, ... Lucas stresses that you should always use FULL STRENGTH nutes. The cyco kleanse may be fine but I have no experience with it. 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. Log in or sign up to leave a comment Log In Sign Up. I've been feeding them PH 5.8 tap water … Running autoflowers, medium Happy Frog soil, fox farm nutrient trio and call mag. Attached a pic cheers. If you are unable to fertigate frequently, then it will be harder to maintain a tight range between inflow and run-off EC values. We used a 1 gallon pot of coco for each test. I grow in coco so I can see how they react within a day or 2 normally. This buildup persists for a while, and then slowly dissolves back into the runoff, resulting in a higher PPM. Long story short, check your run-off at least once a week to make sure your within range. But how can you determine the dryness of your coco coir? I grow in coco so I can see how they react within a day or 2 normally. Start with the LOW end of the Recommended EC/PPM Range. My tap water is PH 7.5 reading 199PPM. hide. I read somewhere else the ppms are low because the nutes are being used up? That's the only reason I suggested the 1/4 strength nutes for flushing. I found feeding lower PPM (in strain specific cases) that i was having more deficiencies . keep flushing until your run off ppms are very close to input ppms. Around 400. It happens fast. I water with nutes every other day. 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.

Always so they been veg for a few weeks since and seem all ok now. Remember that the run-off EC is the value that you need to control. So I flush with 300ppm 6 gal of solution per plant, checking ppm run off at 2 gal, 4 gal, and 6 gal. I’ve really fucked up my pH! The increased water that is taken up by the plant and the increased evaporation causes the EC to rise between fertigation events. I figure the soil is much more flexible but would still have an … See our tutorial “How to Manage Cannabis Fertigation by Measuring Run-off EC/PPM”. By Volume of Water Needed: Coco mixed with perlite has the ideal air to water ratio when it is 90%-100% saturated. My girls sprung back to life. Coco nutes should be here Friday. Water ppm readings have applications for both hydroponic and conventional soil cultivation methods. When calculating your target inflow EC, you need to start with the low end of the recommended range. The ideal pH for coco coir cannabis grows is between 5.8 and 6.0 in the vegetation stage. PPM (Parts per Million) levels is the measure of nutrients in the water used to feed your cannabis plants. During the flower stage, optimum parts per million rises to 1000-1100. The lower the initial EC the better. Not sure how much cal mag I should add to the fertigating water. What should my PPM be? Never use plain water in coco until the flush. Ph is also coming out around 6.9-7.0. Why do you suggest quater strength instead? You definitely want a pH between 5.8 – 6.3 (Lower for hydro, higher for soil). Since water is about half the total volume of saturated coco, the amount of water required should be about 5% of the container volume. The EC that matters is the EC of the nutrient solution suspended in the coco at the root zone. Your main management goal is keeping the run-off value close to your run-off target. Ph is within range. Advice/Help. High frequency fertigation is the best practice. As described above, water is removed through transpiration and evaporation faster than salts are removed. Start increasing your PPM by 100-150 until you reach a spot that is best. 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. Thanks for that. This should be rare, and it might indicate some sort of salt buildup at the root zone. Plants that size should be fed and least twice a day to at least 20% run off each time. Lower inflow EC until you can maintain run-off EC in the appropriate range. Convert all values to microsiemens of EC (values in the hundreds and thousands). Was told to not even start Nutes until week 6, wanted to know what I want my feeding schedule and PPM. 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. As I discuss in more detail below, you are always working to maintain EC within about a 300-point range. This is the PH buffer. Every working meter should get a reading of EC 1.0 from this solution . Be patient if minor burn shows as you increase EC. 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. In particular, you should avoid nutrient lines that recommend high EC ranges and frequent flushing. who ever says runoff #s with coco mean nothing knows nothing about growing with coco. I feed at 5.8 and the run off has been 6.5 give or take a point. The Science and Practice of Growing Cannabis. Both heat and low humidity also cause increased evaporation. You probably want a PPM around 600. However, natural PPM is 350 out of the tap. However if you get a PPM of 600 and a pH of 5.3 you are on the borderline of poisoning the plant. 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. PPM stands for “parts per million” and is a unit of concentration. 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. share. 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. I realize there are variables but looking for a basic explanation of how things “should be”. My nutrient feed chart for the General Hydroponics Flora Series nutrients is provided. My solution going in is around 750ppm, but im using cyco so apparently that's equivalent to 1100 or so ppm. 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: my plants are 16 days old and I'm using canna coco with 10% perlite canna a+b 1/4 strength. 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. Lightly wet the coco medium (too damp won’t encourage root growth). Can you take a closer pic of the leaves? But … You should start by checking run-off daily until the numbers become predictable to you, at which point, you can skip days. The best ph for flowering is between 6.0 to 6.2. 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. Checking with the breeder information is best, but as a general rule: Always “listen” to your plants!

What should your coco run off be? Let's say you have a solution with an EC of 1.0. By the end of 6 gal runoff is near ppm of what i put in (300ppm). i check my runoff #s (ph/ppm) every single time i water/feed. As water transpires from plants and evaporates from pots it causes EC of the remaining nutrient solution to increase. 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! No just water, its suppose to clear salt build up and they suggest using it once a week. We have a wonderful community of growers and you are welcome to join! 2. 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. PPM is Higher in your Runoff than Sump. If you are growing a strain that likes “high nutes” then you may increase the inflow target, and work with a higher range. What's your ratio of liquid cal-mag to mega crop? 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. Starting water must be lower than EC 300. i like reading posts from SCMC as he definitly knows what he's talking about. *EC units are expressed in microsiemens. Ph should be 5.8 – 6.0. 750ppm in yet 4000 ish coming out. hi growers. Clearly, cannabis plants enjoy increased parts per million as they grow.

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. We explain the importance of EC in “Growing Cannabis in Coco Coir with High Frequency Fertigation” and “Understanding EC, PPM & TDS for Growing Cannabis”. 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. Discussion in 'First Time Marijuana Growers' started by ElChoppo, Jul 20, 2018. But i get nute burn if i increase anymore so am i fine then? Ppm going in is 750. Do you have a closer pic of the leaves. If you’ve ever flushed a crop at the end with straight water, you would know why. 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. However, tap and well water may be used if they start less than EC 300. I also did a flush today with the same results. great post! This causes the EC of the nutrient solution suspended in the coco to rise between fertigation events. You should also be using a ppm meter to measure total dissolved solids while you’re measuring the pH. If you use tap water, your reading should … Your plants know better than anyone what EC they prefer. At this point you are ready to determine your EC range targets for each stage of growth. Check with the breeder or do research on your strain. Add and subtract EC for each of the 5 variables below based on the particulars of your grow. I'm 12 days from sprout and the leaves on the 2nd node are looking pretty wavy. 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. The founder of I Love Growing Marijuana, Robert Bergman, is a marijuana growing expert … 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. COCO ph and PPM questions. 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. I'm experimenting with both. 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. My ph going in is also at 5.5. Realize: Plants may be burned by abrupt changes, but they may be able to adjust to the new higher levels. We welcome all growers who want to learn, share and grow together!
