Matina Tomato Leaves Curling Down
Does anyone know what causes this? I've been maintaining a temp of 75-79 with a humidity from 40-50 %. My ph is 6.2-6.3. PPM is 600. Under T5 HO lights. I have some jalapeÃ¯Â¿Â½os and sweet pepper under these same conditions, and they are thriving. Any help is appreciated.
