Screw the stretch then.
Full spectrum lighting from the top, the blue & red emitting from the "full spectrum" light only penetrates 1-2 layers of the leaf, the green wavelength will penetrate 4,5,6 layers, and the best ratio for flower growth is 1/2/1 R/B/G, and very little of the red and blue reaching lower parts of the plants or even the sides, flowers on lower parts of canopy receiving a majority of green will grow larf style buds, often lackluster, I supplement blue and red at the sides, I do not want to add more "full spectrum" this would double dose the green which penetrates deep.
By the end of week, I'm looking at bud sites everywhere, the density is exceptional and above what i'm come to expect in week 1.5, it was the like plant skipped the stretch and went right to bud site production.
If you are interested in the plant's circadian clock, then check out Far-Red photons:
"The R:FR ratio of direct sunlight is about 1[.]5 during most of the day, but it approaches 0[.]6 or so during twilight when the atmosphere preferentially scatters blue light and the sky turns yellow and red. This only lasts for half an hour or less, but it is important because plants use these changes to synchronize their internal circadian clocks both with the24 hour day and the seasons. This involves a burst of gene expression activity that is controlled by phytochrome.”

@Ultraviolet, Sometimes I forgot to plan out the best photoperiod schedule and suddenly find myself dramatically shifting the timer once flowering begins. I wonder if hitting them with sunrise/sunset R:FR would alleviate any circadian confusion.
@Natrona, this was my 2 year old dragon willow bonsai, I placed it outside a few weeks back on a sunny day, forgot and it got smoked in a snow storm, thought I'd lost it. Plonked in a copper rod and she came back to life, frankentree.
@Metatronix, Well that's optimistic :)! Every little helps. I found with such a big pot it would allow for unrestricted growth of rootzone, but the water was sitting deep in medium and with the pot taking up so much space it was very hard to keep the medium warm & with very little air getting to where the roots needed it. Prime breeding ground for some bacteria & fungi.
Always been fond of the idea of automating a grow tent for the entire grow, start to finish, the challenge with auto watering was over-watering, this could also dry the medium enough within a timeframe to prevent the conditions for the bacteria n fungi in the first place.
Originally had some ideas for regular-size pots with airstones but then I got stoned and bought a 100-gallon fabric and here we are.
@Ultraviolet, I 💚 the idea ...it really could increase the yields IMO. It would revolutionize the flowerpot industry kind like the Autopot but for soil.
