Quick question Jin .. I'm getting PH drops over nite .. 5.8 to 4.7 or lower. Evening temp 66 .. day temp 72. PPM 800 ish. RH 37% - 50%. No slime or slimey feel to power cord. Roots are all white except a little brown tint to main tap root. I've noticed as the temp rises there's more water uptake as the ppm rises (transpiration probably). Plants are fine tho ... just two brown splotches on the oldest fan leaves.
Guessing the tiny brown splotches are either mag/cal uptake issues due to PH or possible root burn from PH adjustment fluid added to rez .. ?? I was used to PH spikes up due to hot rez temps and subsequent slime when temps were over 80 .. just not used to such PH drops without ppm rising.
