Yield affected with 12/12 compared to 18/6?

I'm having the problem with a gorilla glue I'm growing and she's not flowering. Same thing she showed sex early on and hasent progressed to flower. I've shut the lights on that side of the tent off 3 hours earlier and lowered temps a bit and started feeding bloom nutes to give her a nudge but no luck. I'm gonna have to put her in her own tent at 12/12 I think. It sucks but I'm outta options.

Appreciate your reply.

I can’t tell you exactly what breeder except that they were bought from Seedsman.

I’m wondering whether going to 12/12 for a short period of time works to initiate flowering? Then reverting to the normal schedule of 18/6 etc and the plant will continue to flower. Or revert back to veg.

Well, here's the rub: it's not yet known if this is a later blooming auto, a "throwback-to-photo" auto (genetic), or a packing error with a true photo,... ... We've seen them all in here!
...in the first case, she'll auto eventually = - but we've seen some go weeks and weeks past the expected transition time... meantime you are still guessing, hence the attempts to force it by extended dark cycling... sometimes it works, sometimes not, and it does crappy things like make lousy leafy bud, caught half-way between reveg'ing and blooming, or induces a hermie response,... even if it's successful, you're still in the hole for several more weeks to finish...
In the latter cases of course, it's all in for 12/12, with the mystery possibly unsolved because you don't want to risk grinding those bloom switching gears and cause some sort of FUBAR reaction like those mentioned above-
Make a point of finding out who the breeder is mate, quality is not a given out there these days, and some breeders are showing to be notorious for half-baked genetics,... even some of the very good ones can have bad batches....
Truth is, the auto'ing phenomena is anything but black and white,...there's a lot of grey area in their responses depending on the breeding quality and all that,... more recently, a big head scratcher came up with me, and after quizzing a few breeders, them too: we have had direct auto x photo F1 progeny turn out to go fully auto, which"theoretically" they shouldn't at F1,... IF one subscribes to the double recessive allele mechanism.... other side of that coin, consider Sweet Seeds F1FV line of photo-sensitive strains, which are all auto x photo crosses,....... I love these versions, very fast blooming is what they are made to do vs, their fully photo' parent- ...If you ever want to run photo's, look into them.... Dinafem and Delicious have some too,... DP's Think Fast is excellent!
Sooo, I guess it's up to you to ride this out however you want to, but I hope this does help make things a bit clearer....

Just set up my other tent for the gorilla glue to put her in 12/12. She's a little bigger than I'd like her to be before flower.

I had the same problem with An auto NLights ! It’s 7 weeks ,you can do 12/12 for a week but then if they start flowering you have 8-10 of flowering. And mine wouldn’t stop growing it was like 44” and in the lights ! So I just cut her down and the other 2 have more room !
