Could be a heat spot causing the burn, do you have a fan blowing on that cola?It's no closer to the lights than any of the other colas. Don't know why it burned like that.
It didnt look like it was close to the lights. Thats why i was thinking prune it off, just incase theres a problem that could spread. Who knows, a caterpillar might have nested in it or mold could have gotten in there. It would be best to know whats inside it.It's no closer to the lights than any of the other colas. Don't know why it burned like that.
to me it looks moldy as hell, does it smell like a basement? Carefully get rid of it if it's mold and bleach bomb your room after it's done. If that is mold i can almost guarantee that's not the only bud that has it. How long has it been turning brown?
