im in need of some help, im still relatively new to this been through one harvest. I belive my plants have some sort of deficiency, i just started flowering a few days ago im growing under a 400w hps in a 4x4 tent, temps are between 75-80 with 60% humidity, im using jack all purpose, and just gave them cal mag yesterday. my ph is around 6.3 and nutes tested at 900 ppm. any ideas on what it could be if not magnesium?
How much Jacks did you use to achieve 900ppm?
