I have a chem 91 clone and all the leaves are yellow drying out and dying. The temps are 74F 35H and at night 66F and 45H. Im using Empire Builder soil and i have had nute burn and what i think was a ph lockout this is my first time using this soil and i ran into problems with it. I havent feed this plant in 2 weeks due to nute burn and its just been on a water only diet. every leaf is drying up and curly and falling off. i fed it calmag pure blend pro with distilled water. no pics. its basically all leaves yellow and curling up and they are brittle.
