I am a long time outdoor soil grower, diving into DWC for the first time. (This is my third - maybe last - try with this set up). I bought the “Bubba Kush” clones a couple of days ago. pH is around 5.8, seems hard to keep in narrow range, but I am monitoring it more closely this time. I know I am not being as precise and scientific as I could be in all this, and that is a risk. I do not (i.e.) have a PPM meter. I am using GH liquids, and the first “dose” was 1/3 strength - - trying to follow @latewood and his advice sheet, I have seen elsewhere in the forum.
OK Bottom line what is this and how do I reverse it?
IN advance thanks, and sorry if I am in the wrong spot…
