I've never paid attention to that actually. I'm trying something a little different currently, but I've always plucked a few leaves whenever I open the tent. Looks like you got about 2 weeks before they're really kicking out some leaves. Just keep em healthy now, they're had enough stress in their lives. As long as your humidity and fans are good, you don't really need to worry about rot or mildew or mold or any of that until they're really flowing. So I'd just cut the bottom fans off to make it easier to water and for airflow and then leave them alone. Did you get hydroguard?
