Yellow leaves my little GG2 is starting to lose many leaves (they turn yellow and fall even before drying) while the other is not having any problems (the only difference between the two is the "aggressiveness" used in the LST) it could be due to the flushing done (but less than 5 days ago) 🤔

Yellow spots nute difficiency? Light burn?I noticed spots on both LB and NL that seem look like nute deficiency, my best guess is cal. I will check pH of soil runoff at next watering to eliminate lockout as a possibility. I've heard FFOF soil runs out in about 4 weeks, maybe that? Light burn from water drops on leaves?
