as above only starts appearing after switch..around bud sites most leaves are fine green look , doesn't seem to effect plants really, quality good to great yealds ok depending on strain..sure if found out what this was it would be betterMore pics would help, top, middle and bottom. Plus a pic of the whole plant.
Just going by the pattern of leaf damage and it stating at the top, my guess would be boron deficiency. Look it up and compare it to what your seeing. Easy to fix, just need to start adding in a miro nutrient supplement to your feeding schedule. Might want to start feeding them a bit more and try to raise the humidity.View attachment 3458510

i agree............I honestly wanna say it's a molybdenum issue. Maybe rethink the nutes you're using
