Is this a cal/mag issue? How much and how often should I give it? Going to recalibrate ph pen when sauce arrives. Living soil w/ recharge and NLS flower top dressing. Any help would be greatly appreciated.
Ahh I wouldn’t say cal mag because it’s not the upper leaves it’s the lower. So it’s nitrogen, but you just started to flower. Get a ph pen for sure. Feed this lady a bloom tea and reset for early flower feed. I think you are ok.
Calcium deficiency i would start off giving them 5ml of cal mag to a gallon of water. Have the ph around 6.3/6.5 when feeding. Best of luck the rest of the way.
