My leaves on my cannabis plants started to get this grayish/brownish/yellowish i don't really know what it. It started from the tips of the leaves and started affecting more of the leaf slowly. None of which really hits the base of the leaf.
It has mostly affected my fan leaves, not really any of my tops. Anyway i just plucked them off thinking it was some sort of root rot? burn? deficiency? Nute lock? I don't know. Temps are 75F-82F Humidity at 50% PH: 6.0 (runoff) I feed at 6.5 - 7.0 Under a 300w LED. Nutes: Coco mix /w perlite and lava rocks. Superthrive (Couple drops) Cal-Mag 2-0-0 Organic liquid seaweed 0-0-1 CNS17 3-1-2 Grow Big 6-4-4 Silicon 0-0-3 I think I'm feeding way too many different shits. I need to just chill and give it some Cal-mag + Grow big + RO water? I have about 4-5 different brands going on in my feeding. Im thinking thats a problem itself.. I should probably stick to a few that goes well together. Anywho if anyone knows whats going on PLEASE COMMENT BELOW!! Thinking if i should throw this one away or keep trying.
