And these might be helpful also but don't confuse lux with ppfd or DLI. These are for ppfd and DLI which there are free apps to measure this like photons and ppfd meter

And if your not yet used to it it's a good idea to learn how to check the sex of your plants using preflowering. It's a good skill set and you learn by doing it. A jewlers loup is very helpful (like 10x). Even if you know they're females it's good practice. You can't always get feminized seeds or you might want a male for crossing. The two tiny pistils on the female are a dead give away.

I'm used to photos as opposed to autos. The few autos I've grown always flowered as expected. The conventional wisdom seems to be use 12/12 to trigger try them if they dont and you can try the search function here on that.
As far as the tips did you fertilize recently my understanding is they can be sensitive to too much fertilizer and IIRC it shows up in the tips with yellowing (I think) and curling.
I'd also measure the amount of light with the lux meter to see of your in the right range for vegetative.
Beyond that there is a section under forums called like autoflower infirmary where you can reach out for help there's a lot of great people here.

I watered the other day but I'm waiting on nutes to come in the mail. Is it still in vegetative stage?
If I switch to 12/12 a d they don't flower can I go back to 18/6?

It's hard to tell in your photos but in a few spots I almost think I see what looks like fine white hairs (pistils). Is it my eyes or do you just start to see this. I mean no offense if your already sure what to look for. If you see these its flowering (assumining its female).

Im 60 my eyes aint what they used to be lol.
Like right here where I circled...

If they were mine and especially if they were photos I'd be concerned flipping back and forth from 12/12 to 18/6 repeatedly. It might stress them out. 18/6 with a photo is like sayin grow baby grow and 12/12 is like saying it's fall time to flower. Stress them out too much a photo could go hermie on you. My guess an auto could too...?

If I switch to 12/12 and they don't flower can I go back to 18/6? And do you think this will work? It's the top of that plant

I think its worth a shot and you'll have fun trying that's all that matters.
I think that humidity domes a good idea. If there's no roots it might really enjoy getting misted with a water bottle set to fine spray like 3x a day.

How long should it air everyday? I've read twice a day
