As I looked at the photos I wondered about the lack of air flow- then I read about the veny and fan ! It's a really nice setup- will be looking for harvest photos!
Yes, you have a bumper crop of spider mites- my worst enemy- Once they are that bad it's usually death for the plants. You must not have been watching for all the pests, and they all got away from you. In such an enclosed space they will come around fast- Ypu probably need better air flow from ene to end- one fan likely isn't doing the job well enough. Good luck with it all.
