i know too much ferts right? thing is i diluted and then it burned so i diluted even more with straight water in my hydro system but i didnt flush it out and replace just added the water to it. Yet my leaves are still curling on one of my plants. I just add a new HPS light 150w nothing big but still a step up from the giant plant flouros i was using. I still have the flor. lights next to the plants and the 150HPS suspended above it.
