Autoflower: can I go back to 18/6?

Hey everyone!! Quick question: I have two royal gorilla autos in soil in a 2x4 tent, about 8 weeks in. They are doing great, albeit a little small. One of them just didn’t start flower like the other, prob 2-3 weeks after the first, and still no flower, so I went 12/12 on the light (from 24/0).

I started 4 new autos in coco, in a closet, with intentions of moving them to the tent. Didn’t anticipate having to go 12/12 to get the 2nd plant to flower (it worked well and it’s doing great).

I need to move the new plants to the tent. Will it hurt to change light to 18/6 from 12/12, to accommodate the new plants? Much thanks for any info provided!! I attached a couple of pics, just bc we all like to see the ladies.

If that one not an Auto it will reveg on you only problem, if it didn't flower on it's own it may not be an autoflower for whatever reason.

Guys the OP said "I have two royal gorilla autos in soil in a 2x4 tent", so unless the seed bank screwed up he has an auto that didn't want to flower until it was jump started. Only way to know is revert to 18/6, if it Reveg then cuss the seed bank lol.

Gotta keep reading.
Op also said, "One of them just didn’t start flower like the other, prob 2-3 weeks after the first, and still no flower, so I went 12/12 on the light (from 24/0)."

So this plant thus far has acted like a photoperiod. I would, at this point, trust the plant over the seed seller. Better to finish without problems rather than risk messing it up and falling back on cussing.

Dudes got one tent, 4 auto in Coco coming out of the closet to go in the tent. That's 5 autoflowering so unless my math is stoned catering to the 5 for sure auto and going 18/6 is probably his best bet.

IIRC, the autoflower trait is recessive, so if the particular seed was from an auto accidentally pollinated by a photoperiod plant that would make that one "auto" plant a photoperiod.
If you have the space to deal with a re-veg I would put it on 18/6 with the other plants and watch for signs that it's re-vegging. If it doesn't it's an auto that just needed a kick in the pants to get started.
If you don't have room to deal with a re-veg you can keep her on 12/12 and figure out a way to keep the others on 18/6 till she's done, or you can cull her and go on with the 4 autos you just started.

I had a perverted auto. Didnt flower under 24 hr lighting schedule when its same strain same batch sister plant did. Switching to 12 / 12 in a different tent, it still didnt flower...so I chopped it.
