4 hours of 100w Red Inc's - 4/25w red inc party bulbs (our PAD
light source)

1 hour of 120w BlackLight Inc's - 2/60w blacklight inc bulbs. A
form of SOD (standard outdoor darkness) w/AD dynamics

9 hours of SID (standard indoor darkness)
Dog, I've been squinting at those pictures trying to gauge the progress of the tips in terms of morphology. And something to watch for is small popcorn type bud development if you have overshot the equivalent SID length (~12hrs).

The Dark timing schedule you're using suggests that you need a Red Inc. Time Factor of about 2.5 to 3.5 to hit a 12 hour equivalent total SID target. BUT, Red Inc.'s move pretty fast (fairly low Time Factor) and I think that you're probably overshooting a 12 hour equivalent SID Darkness duration.

So I would be looking at the plants for signs that they are responding to what THEY percieve as more like a 11/13 type SID schedule, which would produce tiny buds that would finish up and slow growth as if ready to harvest, even though the plants could support more yield the genetics on the clock will tell it that it's finished since it percieves the clock signals as telling it that the season is over and it's time to put everything into protecting the seeds (pods) which gives good potency rather that yeild at this early stage.

If you get the feeling that this is happening, I would drop the hour of Blacklights (since they don't photosynthesize anyway) and watch for improved growth (it should get you pretty close), and then if you want to adjust it more, just vary the regular SID time to fine tune it in.

My personal game is to push how much SID I can swap for PAD (Red Inc. in your case here) to see how much extra photosynthesis and improved growth I can get in, but it's you world in your garden (we each are Masters in our own realms).

Time to practice and exercise those Grow Master Brain muscles.

Take Care, Sal.
