Finish me off in the ally

Running a perpetual scrog set up with a few strains. As you know or can imagine timing is very important and hard to dial in. I finally have the room where I want it so consistency is rising with the plants and finishing times. However with the added fun of other strains comes more timing issues. My NLx critical is in the 63-66 day finishing group, I've got a few train wrecks coming through that so far has been finish a little sooner (60-65, only two so far). Just added some c99, no idea on finishing times...Now to the question.. I have my lights off to one side, with a walkway to the veg, and my ac set up on the opposing wall. This makes an ally of canopy and ac/ducting. Underneath the ducting is enough room to fit a couple screen/pot set ups. However they would not receive optimal lighting. In the timing game I HAVE to get plants from veg into the room in a consistent order, but I am finding (sometimes) I have like a week where a plant isn't quite done..but I need more plants in there.

My new idea is to pull the ones that are almost done out from the optimal lighting, and over to this ally to finish with reflected light. This will help me keep on pace and give them that extra week to finish. Obviously light levles and duration decrease during the flowering cycle outside, I've even herd of people turning thier lights down for the last week or hitting them with some different spectrums. Do you think that moving these bitches to the side to finish up is ultimately worth it? should I hang some strip lights over them to aid in this finishing process? if so any recommendations on spectrum (600w HPS flower). Any input would be greatly appreciated, some other ideas would be even better... I find myself thinking about this conundrum in bed, eyes locked on the celling, hoping it dosent start getting light out! Help!

I would place the younger plants in the side area and supplement the light with CFL bulbs around to supplement myself. Finish off those in the SCROG and plan on using fewer strains or strains much closer in flower time. But you have probably figured that out by now.

So Prep them in the ally, finish under full light? Interesting... Yeah I did the one strain all clones for a bit and it was much easier, but what fun is that haha I'm guessing once I get them to all cycle through I'll figure out the differences and it will again be easier.. There is always that one tho.. Maybe it's the closest in the flood and is over watered or doesn't get optimal light or I fart on it to much who knows really
