Towards the end of week 2 after switching to 12/12 noticed this. I think it's due to a humidity spike during lights off when I had the exhaust off. Just one part of one plant showing this and it hasn't seemed to progress or affect the plant in the last couple days. Not sure if it's mold or what, I checked under the fan leaves and didn't see any pests.
