My two ladies have been having some signs of ph problems with spotting and the other looked like N toxicity, but I read up on that and ph issues can cause that also. Correct me if I’m wrong. I just got my PH pen in the mail so I decided to flush my plants and test the run off. I have them in 8.8" pots and I flushed them with a gallon of water. I didn’t want to go over board for my first try at this. I flushed with PHed water at 6.5, assuming the calibration is already correct,and the plant"symph", which was showing the signs of Nitrogen problems had a run off PH of 3.0. As the other one had a runoff PH of 3.1. I am curious to know of what I need to do to fix everything. I know that that is too acidic but I am lost on what I do next I’ve been reading up on it but can’t find anything useful. All the help is greatly appreciated.
