Made a bunch of changes to try and save these plants:
1. Bought a tent and installed it over top of shelving unit - no bottom attached (yet). This solved the light at night problem
2. Fixed AC to bring temps down
3. Full changed water (and set schedule to do so every 2 weeks)
4. Added a wire shelf to support plants
Overall changes made a big difference, but damage from previous conditions still visible in burnt leaves, poor distribution etc.
