GMSgrowsanswered grow question 3 years ago For photo period from sprout in hydro setup.
1st week from sprout you feed at 400ppm 0.8 ec, if their autos start at 200ppm 0.4ec from sprout. If you seen good growth the first week, then up the feed by 100ppm 0.2 ec for the second week. Every week if your seeing good growth you up it by 200ppm 0.2ec , until you reach 800 ppm 1.6ec. With autos you stop at 600 ppm 1.2ec. Your ph should be set at 5.8 through veg mode and 6.3 through flower mode.
