leaves turning yellow? We’re starting to turn yellow Thursday, watered them Friday checked on them this morning and getting even more yellow! Why is this??? I’m growing in Promix Bx, last ph level was at 5.6. 18 hours of light/6 hours of dark... I did add some nutrients Friday, ppm was around 400. Is it due to my ppms... are they too high since my plant is young?? Do I remove the yellow leaves? I water my plants when they feel dry. About every 3 days I water them. Is it due to over watering?
