If it was a photo growing in water start at 400 ppm 0.8 ec and every week you see good growth, up the feed by 100 ppm until you reach 800 ppm 1.6 ec. If autos they start at 200 ppm and you work your way up to 600 to 650 ppm. The ph in veg should try to be kept as near to 5.8 as possible. In flower try to keep at 6.2 in early flower 6.3 in mid flower.
