I have 8 lights three 23w 2700k cfls, one 60w 6500k cfl, and four 23w 6500k cfls in my grow light reflector evenly distributed. I'm using general hydroponics flora series with 200ppms right now. I did have 3 days where I had pH issues (pH kept rising to 7.0 changed water to distilled and problems went away), could that have stunted them?
