You've got an incredible amount of density in that room; that's the main problem I'm seeing in there; I've often got much the same issues here.
I would think about taking that room in layers maybe. Or taking whatever steps are necessary to ensure those bottom areas are getting sufficient penetration to properly ripen. The stage where your at right there seems to be where all the trouble begins with a tightly packed tent.
Keep on top of how high you've got them lights sitting toward the ceiling also, they need some space in there too dissipate the heat well. Don't let them get too hot. Burning up one of those expensive lights would be a difficult lesson. I'm always worried the heat sink spacing; or the airflow over them.
The footprint you've got on them really appear to match up the tent nicely. I've been running two similar units; but mine are solid end to end.

yeah, there's plenty of penetration. the cutoff you see in the front pic is primarily due to my ineptitude with the camera I have. Trying to learn photography and it's hard as shit to get a good shot with light gradients like what is shown. everything is ripening up pretty equal though.
There's so much airflow in the tent, i think the air in there is likely cleaner than the air in the rest of the house lol five fans in the tent, forced intake, and forced exhaust exchanging the air in the tent probably five times a minute at minimum. The environment is stable at 82F and 50% RH, so no worries of mold or dead zones. pics don't capture the dance, but the girls be shakin.
I have been concerned about how high the lights are. I really didn't want to mount em up that high but these girls stretched so fuckin hard I had no choice otherwise I would've had even more problems with foxtailing. luckily the exhaust is pulling right off the top of them for the most part so if there are hot spots, they're minimal. could be better though, i admit that.
The configuration has been a process as well. After a few disappointing runs, i finally put up for another set of the qb's and built frames for them out of some aluminum channel. The overlap is really consistent so there's a solid LUX reading corner to corner across the entire canopy. Total wattage is 720W @ 100%, as confirmed with a kilawatt meter. all boards running samsung 301H diodes with IR and UV. enough light to scorch plants if one isn't careful, it's way more than is needed but I was sick of loose buds or foxtailed, bleached buds because of plants growing too tall.
This run is finally the one that's damn near dialed. Next one should be the home run. And of course, I appreciate the input. It's been a labor of love and it's finally starting to pay off.
