Correct processing for max yield?

Ok guys. Leaning on you a bit because I trust and get great info from you all and appreciate every bit of it.
I have 6 Bruce Banners that are just over 4 weeks and things have been going well and they are healthy and getting bushy. I have done some LST and the number of bud sites have drastically increased. At some previous advice, I have went from 18/6 to 17/7. Where should I go from here to achieve max yield and possibly get these girls into bloom at around 7 to 8 weeks? They are under MH lights currently set at 750 watts. I attached pics from day one until current. Thanks guys and gals!

Just keep doing what you are doing...
Looking great.
Be cognizant of stretch...this will determine plant size in relation to flower area size for vegging size....
If that makes sense at all lol.

Makes sense. Should I dial back daylight an hour per week for the next 3 weeks until ultimately going to 12/12? Thanks for the correspondence!

Go back to 18/6.

Flip to 12/12 at week 7 or 8 for them to start flower if you want them to at that time?

No.

This^^^^ I would stick to 18/6 until flip....stay where your at or do that, but no need to fade down hours...waste of growth time.
