In the last couple days several of my plants have developed some brownish spots on the leaves. Couple have already fallen off. I recently had to set up my grow station in a new place its pretty cold in the room and back under my 400w light. Anybody think this is an issue with some sort of fungus or just perhaps the cold and getting used to the light.
