im sitin at around 5.8 to 6.1 ph, i flushed, added 5 ml of cal/mag, nothing will stop the leaves from curling up and getting cruchy , this started at the tops and moved down the plant, 1 is pretty much a loss at this point now its moving to the next plant allmost 2 weeks after plant 1 started doing it, im at 600 ppm, 75 degrees, good ventilation, co2 running ,, im not sure what to do,i've tried everything i know to do ??

checkin in on you, brother. get that ph rized up?

remember, give the plant a few days to respond. whenever you make your solution, never hurts to add3-5 ml of calmag. way under the recommended dose, like a safety net.
