Seeds from Amsterdam Seed Company, and was let down by seed viability. 1000 watt HPS for flower, vegged under 125w CFL, then 500 w and later 1000W MH. Grow media is Sunshine Mix #4. I use the attached GH schedule, and the only supplements I use are the Floraliciuos Bloom & Grow, and Kool Bloom. Switched to 12/12 light cycle on May 15th. I know if I dilute my hard well water by 2/3 with rain, it's about 200ppm TDS(Ca/Mg mostly). I do use Hard Water Micro. I never measure pH, or nute TDS. I water by weight during the week, and flush well with full strength nutes once a week. The Sunshine mix is an inert hydroponic media, and not a soil.
