I recently transplanted 2 Banana hazes from solo cups into these 1gal. 1 is coco loco the other is promix with nothing added and a half cup of expanding clay pebbles mixed into the soil. I transplanted and fed with 3ml of advanced nutrients connoisseur grow A+B 3ml of each. 1.5 ml of cal mag and great white sprinkled on roots at transplants. They were doing great. After clearly dry and sagging Watered with just RO water and calmag and the next day mainlined both as they looked very healthy and growing fast. They both recovered and looked good for 2 days and then this. The one in promix has these spots on the leaves that looks to me like I've overwatered.. BUT they were drooping and the soil sensor with the 2 long metal probes confirmed dryness. Ive been having similar problems with these other 2 that are also in this promix.
