Well, you wanna make sure that you only feed pure water the last few weeks, to ensure that you don't get bomb shit that tastes like shit and turns into a black rock when burnt. I would say if you made it this far without it, hold off till next grow... Your next plant will be that much better! Just my 2 cents worth though.so today i got my big buds in the mail. its pretty late now. im not sure if im going to use it or not. im might have time to use it once or twice. what do you guys think. i plan on buyin a microscope soon so i can get a good look at the trichs. that should better help determine if i use it or not.
let me know what u guys think
