I start with 2 grams per gallon up to day 15, then a week of 3 grams at day 20, after that I use 4 grams per gallon till about the last 2 weeks when I back back down to 3 grams and bump up the bloom booster. But this last run I stayed at 4 grams till finish with GreenLife Biotics Bloom P17/K17How much mega crop you run per gallon?
