I am approaching week 5 of flowering, these leaves are from 3 different strains. 1 is AK47, Permafrost and the other is a mystery strain. Each plant seems to be having the same problem. These leaves are looking awful and a few on each plant seems to be giving up and falling off here and there. 80% of the leaves look fine as well as the buds, but a lot of them are turning into the leaves shown in my pics.
Is it nute burn, deficiency, fungus or root bound? Possibly heat stress? I have no problem growing in veg, most of the leaves look great., but now approaching the critical stages of flowering I am starting to have major leaf problems. I grow in FFOF (nothing else), using BMO nutes with Calmag every other watering. Temps are usually between 70-84 degrees on average, RH is 50-60%, ventilation is pretty good with lots of air flow. My water out of the tap is 7.0 PH. I let it sit for 3 days before I use it and the PH to about 6.0 before I feed.
I feel like it's a single problem that can be diagnosed and fixed with the right advice. I hate to be one of those guys who says he's desperate, but I am at my breaking point trying to fix this problem. I've taken a sample leaf from each plant to show the problem. Any help will be greatly appreciated. Thanks guys.
Notice the yellowing on the one leaf, and the small brownish dots on others. Ugh.
