Hi IC,

Been vegging about 3 weeks and starting to get a few small brown spots on some fan leaves. I want to fix it before it gets worse. Had some issues with too intense of lights early on which fried a few leaves but things have been looking good since. Hard to see in the pics. Easier to spot in real life.

Any idea on what might be causing these brown leaves?
