Can't get easier than maxi bloom, don't even need to buy maxi grow. You can use straight maxi bloom full cycle, don't even need cal mag if your on city tap. I ran out and bought mega crop 2 part, haven't tried in dwc yet. Buy a bottle of southern ag garden friendly fungicide to prevent root rot, very cheap, you only need 1ml for every 5-10 gallons. And Chang the nutes every week if using bennies
