8 weeks old and no flowering???

They look healthy an auto should flip on it's own. I guess I'd give it like another week. Then I'd go 12/12 but it's gotta really be dark for the 12 off for that to work. I'd give those seedlings like 18/6 though if that is a seedling I see in the background

Yes it is and I only have 1 light so that's why I was waiting to start new plants

I just switched to 12/12 today should I go back to 18/6 for another week or so?

Yes thats a seeding in thr background the stem is seriously thin at the bottom from where I bent it but it's still alive so lol

The thing is using 12/12 is sort of like tricking it saying hey look it's fall time to bud. It's a trick myself and many others have long used for photos.
My guess is this works with autos that are hung up (?) and need a push to get them to flip into budding.
Personally I like my seedlings to get 18/6 or even 20/4.
I'd consider a small led for the seedling that can supply it with say 200 to 300 PPFD.
There's a free app for phones to measure PPFD if you don't have it (PPFD meter or photone).
I use a couple of led strip fixtures for this and they only pull like 30W.
If that seedling container is small enough to easily move.. I guess you could try time it so you move it to say a window sill to get the extra hours of light but I'd watch for stretching (like 12 in the tent and 4 to 6 in a window sill).
Also I should have asked but are those seeds feminized? I can usually presex mine between 3 to 5 weeks. I'd hate to think your creating a lot of effort and it turns out it's a male

I have a Lux meter I don't know if their female I assume they are sense they were seeds my experienced grower friend was going to use himself

That's cool I don't have a chart on me but if you search here or Google seedlings and lux I bet you'd get a decent answer. I seem to think it's like 4000 to 7000 but I'm not really sure best to check. Just get it in a window for the hours your keeping the big one in the dark in the tent

Hey any updates? How are you making out??

I decreased to17/7 on the light to see if that will trigger flowering and topped it for the first time sunday but of course I can't tell a difference it'll be 9 weeks old tomorrow

I think the light might be to strong the tips are yellowing?

 

[Kirka88]

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.
