i wish you good luck. Veg is 18 on 6 off, for me. I feed mine Fox Farm Big Bloom, and now Fox Farm Big Grow.. Than Fox Farm Tiger Blooms in the end.. great system.. ph is good between 6.3-7.0 depending..I think distilled water is the best.. dont buy.. fill up gal. jug let it sit covered room temp for 24 hours. That distills it. Overwatering is a problem to.. I cant wait to see my girls..Bubba Kush.. cant wait.. one is my avatar. Good Luck! :jointsmile:
