Autoflower light ratio

Hello,
The thing is about Nirvana Short-Rider. it vegetated at 18:6, when it was about 11 inches tall switched to 12:12 for flowering, now the buds are pretty small, pistils are mostly white and the trichromes are clear transparent. So today I read that for autoflower strains you can leave 18:6 all the way from seed to harvest for bigger yield. So is it too late to switch back to 18:6? I mean is there a risk it will go hermaphrodite?

Some autos you can even keep for 20/4, I've even had them at 24/0 before.

But... You're fine to switch to 18/6. Autos are resilient against light stress.

So it will be ok if i switch back to 18/6 after it has been in 12/12 for about 3 weeks?

Yeah, I'd go for 20/4 though.

Read first next time but autoflowers flower automatically. Hence the name and the key selling point for many. Germinate them and run them anywhere from 18/6 to 20/4. Or even 24 if your electric bill can handle it. Personally I think even plants deserve a break but then that's me. I get rewarded by them come harvest.
