I have 36 plants in 3 gallon pots under 1000w hps bulbs. They did great through vegetative growth and looked really healthy up until about two weeks into flower, although I did not get the additional growth spurt I usually get in that first two weeks of 12/12.
Starting week 3 yellow leaves started showing up, has continued to get worse, yellow,curling, brown and grey leaf edges. Also,the overall color of the plants has turned to a bright neon like green. I was feeding 20-20-20 for the first week into 12-12 then switched to my regular flower food, (optimum hydroponix flower). I have tried swithcing some to straight water, someback to20-20-20, and some i have kept on the flower food, yet almostuniversally they seem to be dieing off. I have no signifigant presence of mites, temps are running at about 85 day and 75 nite. Anyone with suggestions oranswers please help. I appologize for thepic quality but hopefully u can still get a good idea of what they look like.
