So I'm on my second grow but my first photoperiod, been following dr mj coco and his suggestions on high frequency fertigation as it seems the right way to go with coco coir. Been mainlining and super cropping, hence all the bent over tops and what not... seems to be going well but I'm seeing some strange things going on with certain leaves and some are much darker than others. I have been thinking it's down to either a cal/mag deficiency or bit of nitrogen toxicity. It's not too bad but I want to catch it before it gets worse. Followed the canna light feeding in soft water schedule with their whole line of additives and a and b. My water is low ppm at 85 to 90 ppm, checking runoff and it's coming out at 900 to 1000pm everytime and I'm feeding it with 600ppm. Do I need to just back off a bit on the a and b or add cal/mag as a supplement? Any help would be great thanks!
