GMSgrowsanswered grow question 4 years ago Hydroponics, 400 ppm 0.8 ec to start your babies, ph to be set at 5.8. Increase 100 ppm 0.2 ec every week until you reach 800 to 900 ppm. 1.6 to 1.8 ec. When flowering starts increase your ph to 6.2 and lower your flower nutes to 700 ppm 1.4 ec for the start of flower, increase to 800 ppm for mid flower, only go higher if you really see they need it. Recommend either canna aqua or Dutch nutrient formula. Both specifically formulated for hydroponics and both have all your plants will need for great growth and big buds. Cheers
