if your sexing the plant, as you will hear different stances on this, let me throw my two cents in! sexing then putting your plant back into veg state effects the potency of the yield hands down!

for neuts i used MG for hose hold plants and for flower i use shultz 10-54-10 bloom booster it seems to work awesome .
