dude anyone who doesnt flush is an idiot...unless you like your buds to taste badYou got any pics bro? And no flushing is not needed with the BMO. Personally I think flushing is a lot of work for nothing. I just up the amount of pure water the last two weeks a half gallon each watering and don't go pouring 20 gallons through the soil at once. Anyways with that said a bit less than the reccomended amount of dosage per gallon and youll be good. Also early in flower your gonna have to pick up some dolomite lime for MG and CA cause BMO nutrients are low in it.
