Dude! I would recommend organics in your arsenal with molasses and a organic micronutrient and Micorhizzal and hizzae benificial bacteria tea worked in between. Never any granulated or crystalized stuff just mixins and bubbled teas! You won't need to flush(but I do anyways) and right when you hit maturity the fan leaves should be the same hues as autumn leaves. Yellows, oranges, purples, and even pink and reddish hues. This takes practice though. Right now my lower plant fan leaves are dropping right on time and the buds are pushing out super amounts of calyxes and pistils galore and they are still a month to finish or so.The only thing non-organic is a touch of Superthrive at a few crucial points in plant development.
