Auto late flowering?

Looks like it's getting there. A few things can affect how quickly an auto develops. I have an auto right now that's developing slower. Same genetics but because of other plants, I wasn't able to give it as much light. It's about 2 weeks behind the others. If your plants have already stretched, switching to bloom nutes and cutting off most of their N might encourage them to start focusing on buds. As long as your nodal spacing stays good, I wouldn't worry.

Sometimes they get more genetically inclined to their photodependent parents and the ruderalis trait doesnt get as much dominance as it should. Try flipping to 12/12, but if you are outdoors and have no space limitations, id say let it rip, let her grow to monster buds, get a massive harvest even if it takes a while for the 12/12 to come naturally.
