@Portnugs, that was my first assumption in my case too. I didn’t flush, but I did when I got locked out from ph swing a few weeks into flower. It helped to get her feeding a bit again but not with ph. I had an issue a while ago with fungus gnats I knocked down with azamax (they are back but too late to treat again so just sticky traps), I had read a case with someone in same situation, tried all the things and was suggested as bad bacteria in the res and do h2o2 flush. I was dropping point plus every 24 and losing leaves so I figured I treat and possibly kill the plant or I do nothing and it kills itself. Did the flush, reintroduced my bennies and added cannazym to clear dead organic matter and cut my ppm way down (was running too hard tbh) and everything has been stable for the first time since early flower! Hope that helps, it was scary lol. Start with some flushing.

Thanks @Gzuscamp! I'm still getting my head arround this negative ph drift! BTW we're you flushing your medium before flowering? I did no flushes and am wondering in accumulation of salts in the medium could cause this issue but not sure.

@Ga4rd2en0er, thanks for the heads up it's my first Hydro grow and I defenatly had some interesting experiences with ppm and ph. Actually I started this week at 1100ppm and noticed a ppm natural increase to 1200 so 8 lowered to 1000 and noticed a big difference. I think I was on the red line. Think I will be keeping steady now at 1000 until she starts asking for more food.
