I assume you're just doing DTW in coco? IMO, and some might disagree with me, but I would run drip clean @ about .4ml per gallon. I would do multiple feeds a day once the roots are really establish and not even worry about run off.
Do research on multifeeds with coco and also search no run off DTW. I'm setting up my new room this way and have 2 friends that have been doing it for a couple runs. Explosive growth, simple drip system and very little runoff if any.
