hello, and thanks in advance for any advice. was hoping somebody could dx the issue based on the pics/stats.
gonna try and keep this short and to the point.

system: air assisted atomized aero
nuts: canna substra soft full line in 50% RO water + added cal mag which is new this run, temp-68, ph 5.8, EC 1.5, drain to waste
atmosph.: cge, temp-75, rh-55, c02-1200ish
plants: og kush and blue dream, first time using these strains, started vegging on dec. 15

anyway plants are looking progressively sad and wilted. room is bug/mold free. roots look decent, chamber temp is in low 70s

only thought I have is upon recalibrating my ph meter it was off. so nut ph had been down to 4.9. I corrected this and flushed with h202 for an hr. that was 3 days ago and plants and still looking worse. are they beyond repair or are the symptoms not even related to ph?? would like to start flowering as the screen is already 75% full but want to get the girls healthier first.
Thanks again.
