GMSgrowsanswered grow question a year ago When looking at your diary, the one filled up to where you can see the water, that water is to high. Also your buckets being homedepot orange will let light through to your roots. This is also not good. Maybe wrap some tin foil or duct tape or paint them black. Also in hydroponics we feed from day 1 and we start at 400 ppm, 0.8 ec for photo period plants and 200 to 250 ppm, 0.4 to 0.5 for autos. Increase 100 ppm 0.2 ec once every week if you see good growth. Autos can go up to 600 to 650 ppm 1.2 to 1.3 ec only more if you see they really need it. Photos can go up to 800 to 900 ppm 1.6 to 1.8 ec. and only more if they really need it. Try to keep your chiller at 58
