Air Flow Question with CAD / Drawings of My Grow Setup

Hello,
This is my setup. I have 2 grow rooms (larger top left and right rooms). And a veg room. Each room has 24 plants, RDWC. In the bottom left closet I have my reservoir / reserve tanks. Outside the closet door is a 1 HP water chiller temps set to 65ºF

Each grow room has 6 1000w HPS lights (outlined by the square foot print) My veg room has 4 ts1000 lights.

In the top left room I have a 30,000 BTU mini split. Also in that room is a 12" phat fan / filter that is ducted so it pushes cold air into the top right room to help cool it.

Each grow room has 4 hurricane oscillating fans (2 per left and right wall)

Right now I only have vents to help the air flow into the veg and back into the top left grow.

Only one grow room is on at a time. 12 on / 12 off
My temps in my top right room are approaching 82-84ºF during the 12 hour day cycle
This heats my veg room to 78ºF
My top left room maintains 73ºF during the 12 hour night cycle
I run my minisplit 24/7 at 68ºF

My question is, should I add another 12" phat fan / filter, and push/exhaust the air from the top right room back into the top left room, to create a constant clockwise air circulation or is there a better way of doing this? I'd like the two grow rooms to stay under 80ºF

Room sizes are approximately
Top Left (21'x11')
Top Right (16'x11')
Veg (7'x11')

This is in a basement. I wish to have maximum odor and temp control

If you add another filter/fan to the 73 degree room, set up similar to the one that you already have, and only run it when the 82 degree room is in the lights on mode, you would increase the air flow into and out of all of the rooms. The increased air flow should help to even out the temperature in all of the rooms?

i actually had another 8” fan laying around and tried this today. It didn’t really change much. It seems I need to exhaust the hotter room somehow. I’m thinking of trying to exhaust it through a HVAC vent to the upstairs to keep my house warm during the winter and my central air can offset in summer.
 
I think 30,000 may be right on the cusp of tolerance for 6 hps. If the minisplit is set to cool the environment to 68 degrees and is not doing so if maybe potentially overworking your compressor. I run 24000 for 4000w hps rooms

Run another opening from room A to B, put 4 fans on the minisplit wall. So it can help blow cool air to the plants and to the next room. 4 more fans In room b.
