GMSgrowsanswered grow question 4 years ago You need to decrease your ph down to 5.8 and your ec up a little 5 to 600 ppm 1.0 to 1.2 ec. When new growth gets better then increase your feed 100 ppm every week until you hit 8, maybe 900 ppm, 1.8 ec. When you switch to flower you need to then decrease your bloom nutes to 1.4 or 5 ec 700 to 750 ppm. Work your way up every week 100 ppm until you reach 8 or 900. Cheers
