Looks beautiful and healthy. Couldn't ask for better.
My only comment is it's packed pretty tight. From the number of stems coming up from the pots it looks like lower flowers are buried in the fan leaves of the buds at the top. IMHO you could clip and/or tuck fan leaves above and get some light down to the second tier of flowers below. Also, with that density of flower they're going to need plenty of air flow, good fans.
Maybe I don't understand your method so trash that comment if you like.
If you're in a state that allows it you could go SOG next time to maximize yield. Small pots, as many as you can fit, flip in a few weeks, no training, one big central cola per plant. Should be a little quicker too.
I have a 2x4 and I find that with nice healthy plants in a LST, HST or SCROG situation, it works out better for me to have 2 plants in that space. If I do 3 or 4, individuals don't have room and I'm planting more seeds, watering more, but not getting more flower. I have a SCROG going now and just flipped a couple days ago.
Looking forward to seeing your Bruce Banners finish! It's gonna be big!
