Is this flowering on 18/6?

[SGD]

My bag seed plants are still on 18/6 light but one of them has started to look like it is flowering. Is this the sign I need to switch to 12/12?
This plant has been growing more vigorously than my others (about 50% more veg height) and the other two are not ready to be switched yet so, I'd prefer to wait until then.

Could be a male look real close for male parts. If you switch to 12/12 you will definitely see the sex of your bag seed. Can you isolate it with just a CFL light till the sex shows more?

Could it be an auto? Think i see white pistils when i blow pic up.

[Farmbuck]

I agree with buds73 look like an auto.

[CaptainWiese91]

Definitely a girl. And I do agree then it must be an auto flower

I'd say it's more like the plant telling you it's sexually mature, so it's throwing out pre-flowers.
All of the mothers in my veg tent have pistils.

All three of my plants have white pistils which, if what I've read is correct, makes them all female.

If my bought weed was grown from an auto flower but has a few seeds in it does that mean it was pollinated?

My other two plants are starting to show the same 'pre-flowers' but are about a week or more behind the one in the picture. Can I get some advice on whether to switch to 12/12 or wait please?

[ChadWestport]

Yes, the pistils make it a female plant.

Yes, if you pulled seeds from the weed you were smoking, it was pollinated. By what (auto, photo, male or herm), no one knows.

If you have autos, the duration of day and night will not matter. You can stay with 18/6 until you are convinced they are autos and female and then switch to the 12/12 schedule.

Autos dont need to be cut back to 12/12s, they will flower out at 24/0.
How old is the plant in question?
Autos start to flower at 3-5 weeks old and finish on their clock (56-130+ days from sprout). Photos can put on preflowers under long hours of light as well, that does not mean you must switch to 12/12s. You can keep a photo in veg forever, flower it and veg it again. I seeded 2 plants took the seed pods off and then grew flowers for harvest with no reveg.
As said you know more about the strain then we do, you know what 1 parent was, did the grower know what the other was, who knows.

Hey, thanks for the info.
Rwise - My plants are around 10 weeks from germination. Does that mean that they not be auto-flower then?
I had an issue with over watering right when I was transplanting them and that slowed them down for about 3 weeks. Here's what my other plants look.

[CaptainWiese91]

10 weeks in veg, then they are mature enough to show pistils. Mine did too after that long veg time

[Rwise]

Not autos, drop the lights to 14/10s and watch what happens! At this point they are ready and want to do their thing.

[SGD]

Well, I guess this settles the question about it being an auto. It's a boy! Now removed from the tent.
Is it unusual to have pistils on a male plant?

[Rwise]

A hermie will have both, and would explain a seed in the bag, daddy was a hermie.

And mama was a rollin' stone, lol.
