I've used a scope and can't find any broad mites. I can't think of what else this could be. They're spitting out perfectly healthy 7 finger leaves, the wilting up every three nodes of growth basically. So it's just chasing it upwards. Since they're spitting out perfect green leaves I'm assuming that means it can't be ph, nute issues, root lock, etc...only other thing could be bugs correct? Actually as I'm typing this I'll say my humidity sucks and is between 10-30%. Could low humidity be THAT bad?
