I have been battling higher than recommended PH I keep feeding and flushing with lower PH but it keeps steadily raising back up.
Im finally updating! Things got better but it was hell these next 2 weeks... high Ph with low ppm
So I mixed a ½ gal solution but adjusted it by adding water to ⅔ gal to bring down the initial EC/ppm testing at around 1400/700. I ph to 5.8 and fed, the runoff was shy of 20% testing at PH 2.65 EC 3940 ppm 1970 Why and how to fix?
Overfeeding. Flush with regular, ph'd water until the runoff is where you want it. With your pH so low, I would run 7-7.5pH until its back where you want.
When you overfeed, the plant takes up water and leaves the nutrients. Most nutrients are acidic so your runoff becomes low pH and high EC.
