what kind of drip system are you speaking off? I use a 6 pot rainforest drip system for my mothers. I use a timer set at 15 minutes on every hour. (15 min on - 1 hour off - 15 min on - 1 hour off ect. As far as nutes. I start them off at 2.5 ML/ gallon for each nute (micro - bloom - grow). I'll post the chart I use a little later. Once your mothers are well established you can get away with pretty much just feeding them ph balanced water for a few days at a time.
