Im growing in coco In autopots under a qb 3500k 240w from alibaba.
right before flipping to flower about a week ago started noticing the new growth is very lime green almost yellow and the plant is growing extremely slowly and barely drinking anything from the autopots, new shoots arent growing much as well and the tips on the new growth are burnt? Not sure if this is due to lockout from autopots but it kinda looks like burn from too much PK or a sulfur deficiency? Manganese or Iron deficiency? Im feeding at the recommended 1390 EC my base water is 200 EC so 1590
Could I be mixing my nutes wrong? I add 4ml/gal calimagic and which gives me about 600-700 EC and then I add mega crop until I get too ~1.5 EC, When I add the recommended amount of grams to my mix after I cal Mag I end up with a solution around 2 EC which is way too high? Am I supposed to cut the cal mag and use only mega crop? I have sweet candy as well but I haven't used it yet. I top flushed a few times so maybe I flushed down the salt buildup from the top of the coco into the root zone but I highly doubt that cause my runoff was 1300EC and I ran 5 gallons through it. Im using Hydroguard as well so it cant be root rot.
someone please help I have no idea what to do to correct this, I had one or two fungus gnats so I dusted the top of the coco with diatomaceous earth and i got a bunch of yellow traps which havent caught anything in a week so i doubt the problem is bugs.
