Having this issue and I cannot get to the bottom of it. Looks like late stage K deficiency??? I was having PH dropping issues 2-3 weeks ago which caused some deficiencies but i have now got stable ph 5.7-6.2 daily fluctuations and a steady e.c of 1.2 so I can’t see why the issue is there?? Am I missing something haha. Not sure what to do. Also unfortunately think it’s probably gunna be quite hurtful to the yields :(

Have begun the flush. After 24hrs thinking of backing off to 0.8 ec. Background tap water is 200pmm so will only be adding 200ppm of nutes

Judging by the clawing leaves and necrosis all over the edges there are some PH Issues and Nitrogen Toxicity.

Feed half strength and see if they improve as others have said.

lol added to list of reasons I grow in coco.

Doing a change now after a flush. Going to go for 0.7 ec of just a+b (dutch pro nutes) no explode ph-5.8. Not sure what to expect really. Due to being mid to end flower will they green back up or now being yellow they won’t get any better just shouldn’t get worse
