I cant, for the life of me figure out what is going on here ,leaves up but curling .everything else is fine .
Temp in room is 71.1
Ppms now 515 . Res. Temp 65 .ph 5.8.
Vegged in the room in pic,brought outside to flower and the leaf curling started . Only .moved indoors during hot times of day to see if temp was the issue or ventilation cause it was doing great indoors. I've heard russet mites but I've had em once n this is different. Again 1st pic currently ,2nd pic was during veg.indoors only .
