So I am struggling at getting my PH down. Would like to hit 5,6ish going in. Currently at 5.9 with 1300 PPM. 2 weeks into veg so I don’t want to over due the PPM. I have used GH PH down and Advanced Nutrients PH down. But still getting 6.3 out. Running coco with perlite and some worm casting. Also the soil that was on the plant in the 3 gallon. Currently in a 7 gallon fabric bag.
