Hey, Def a a little bit savage from an experienced grower imo I'm not here to put any grower down and I'm sure Mrs Larimer may look and say hey you know what maybe I was a little bit harsh there, but the second response makes me think he/she has maybe thought that, I don't know!, But like I said I'm not here to put 'anybody' down or judge yes you have xyz diaries and yeah you might not have experienced this issue before, but hey that's life and what 'questions' are for!! IMO maybe a little heat/light stress which is common on the canoeing of the leaves, the spots could also be related, as I'm sure you have the knowledge from the amount of harvests you have to know what you are doing with your feeding etc... Maybe this particular strain is a little more sensitive then what your used too! Go back to basics look at what you have feed, training etc and see if there is anything that 'pops' up that makes you think, S**T yeah I did this and correct it as you go, hope this helps happy growing đ
