there is really no need to foliar feed unless you are trying to correct a defficiency. it is possible (and probable) that you are clogging the stomata by feeding 2-3 times per day. this in-turn would block the uptake of your co2.

temps should run around 85-90 to take advantage of co2 supplementation. are you running a sealed room? or are is your exhasut on a timer?

you called yourself a noob? how exactly new are you?

did you soak the "grow cube"? can you define "grow cube" as well. jiffy puck, rapid rooter, rockwool etc....

you say you are running DWC yet say that you feed ten minutes every three hours. and you are fogging the roots? can you elaborate on this.

are the roots staying in 100% humidity?
