Grow in soil and you can dispense with 3/4 of your nutes and pH becomes a relatively minor issue. It is very forgiving. I use FoxFarm Ocean Forest. I don't need to nute at all during veg although I do provide a few additives for enhancement. In flower I nute 4 or 5 times @ progressively higher does up to maximum of 10ml / gallon. I've left my girls for a week without water without issue. It's so low maintenance that can go days without looking in on them. Well I could except I'm like a mother hen...
