So, I recently upgraded from (1) 4xT8 grow light in the closet to (3) 4xT5HO lights over a 6' table. Not sure if that may be a factor, but it's certainly warmer under the lights now! My plumies (12) mostly have whatever soil they came with, I water once a week. I've had to use neem oil occasionally, and a little 3-in-1. In the last week or two, I've had a lot of fungus gnats (seems like certain plants are infested), spider mites, and now I think rust! Even my "rust-resistant" Jubilee :( I've been using a "Bt" spray on the soil for the FGs, not sure if it's working, there were a bunch of them flying around today! The spider mites don't seem to be a huge problem ATM, but in the last couple days I'm getting rapid leaf yellowing and spotting (see pics) on several plants. Rust?

Here's my grow setup. Lights are on from 6:30AM to 9:30PM.My Jubilee :( It's certainly too early for dormancy, right??My Dynamite. This has happened really quickly :(On the plus side, I think my little pineapple is almost ready to ripen! w00t!!!

I'm up for any ideas. Too hot under the lights? Not enough water? Too close to the lights? Too much light?Take 'em all outside for a 3-in-1 and neem oil bath tomorrow? Change out the soil for the FGs? Kinda rather do that during dormant season. Any help is appreciated :)
