Ok heres the low down. There outdoors, i was using chicken poop as fert then moved to 9/12/12 and finally i just bought some 15/30/15. I water every 2 days sometimes everyday. It has been 90+ most days. They just started budding. I first thought the problem was heat so i was giving them more water each day. Then i thought they needed epson salt. Tried that did nothing. So i dont know what the problem is. Heres a picture of a leaf i cut off. It has began to spread all over my plants. Any ideas?
