It's not close to the light at all. Actually I think I fucked up that fan leave because it was tucked under my screen and I pulled up up through the screen yesterday when I watered it. Maybe that's it. I'm not to worried as this is litterally the only hole I see anywhere at all on my plants. Was just curious if somebody knew what it was. Also I'm using the FF Trio. No nute burn on any leaves or anything. Searched aain for bugs but still didn't see any. Who knows. If I find some on other leaves i will worry.
