what should my ppm be in coco
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. 750ppm in yet 4000 ish coming out. 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. Depending on your plant’s maturation and the number of nutrients it can absorb, the ppm should range from 750 ppm to 1500 ppm. You definitely want a pH between 5.8 – 6.3 (Lower for hydro, higher for soil). Convert all values to microsiemens of EC (values in the hundreds and thousands). If you are unable to fertigate frequently, then it will be harder to maintain a tight range between inflow and run-off EC values. However, you can only measure the EC of the inflow and the run-off. I’ve really fucked up my pH! Be patient if minor burn shows as you increase EC. I wouldn't worry about the ppm's but the pH is a problem. But i get nute burn if i increase anymore so am i fine then? Your main management goal is keeping the run-off value close to your run-off target. 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. This should be rare, and it might indicate some sort of salt buildup at the root zone. *EC units are expressed in microsiemens. My ph going in is also at 5.5. © Copyright 1999 - 2020 Grasscity.com is a part of, (You must log in or sign up to post here.

Lightly wet the coco medium (too damp won’t encourage root growth). whats up dudes? I hope this issue works itself out. Slow the increase and allow plants to adjust. However, if the supplier recommends EC ranges that are significantly higher than these general EC ranges, I would recommend finding a different supplier. Sounds like I've been running my PPM way too low. The "EC-to-TDS Conversion Factor: NaCl (avg. I realize there are variables but looking for a basic explanation of how things “should be”. Coco coir retains water well — too well, if you’re a cannabis grower who tends to overwater.

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. 400 microsiemens = 0.4 millisiemens. In the chart below, you can find general guidelines for optimal EC at different life stages, however, there are differences between different nutrient lines. Your plants know better than anyone what EC they prefer. The key consideration is the EC. 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. I've been pinching them out and lollipoping they now been in flower for 2 weeks. If however the runoff starts off low or at 1,200 ppm you can take your nutrient load up a bit. 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. Slowly run 2x to 3x your container size of plain pH’d water to really flush it out. 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. COCO ph and PPM questions. Yess finally buds are on there way. 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. keep flushing until your run off ppms are very close to input ppms. 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. 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. However if you get a PPM of 600 and a pH of 5.3 you are on the borderline of poisoning the plant. Add and subtract EC for each of the 5 variables below based on the particulars of your grow. Was told to not even start Nutes until week 6, wanted to know what I want my feeding schedule and PPM. No just water, its suppose to clear salt build up and they suggest using it once a week. 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. 100% Upvoted. 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. Long story short, check your run-off at least once a week to make sure your within range. My head hurts from reading so much about pH, PPM and EC. We welcome all growers who want to learn, share and grow together! Remember that the run-off EC is the value that you need to control. What should my runoff ppm be in soil? My solution going in is around 750ppm, but im using cyco so apparently that's equivalent to 1100 or so ppm. 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. Ph should be 5.8 – 6.0. Ph is also coming out around 6.9-7.0. 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. 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. It is set for the standard EC targets, with no grow specific adjustments. I suggest you flush with 1/4 strength nutes instead of that clearing agent. I grow in 3 gal pots of coco. 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. Santos L Halper Member. i check my runoff #s (ph/ppm) every single time i water/feed. 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. Advice/Help. hi growers. Start increasing your PPM by 100-150 until you reach a spot that is best. When calculating your target inflow EC, you need to start with the low end of the recommended range. This causes the EC of the nutrient solution suspended in the coco to rise between fertigation events. If you have plant nutrient recommendations in EC units, an EC meter is convenient.
