Girls started flowering without 12-12, Not Auto's

I know they're not pre-flowers cause I saw those about 3 or 4 weeks ago, they have been on 18-6 since day one. I guees my question would be, do I leave them on current light cycle or switch to 12-12, it's been exactly 65 days since they came out of soil. I got them from Herbies, a couple were fems and some were just regular seeds, I didn't get any Auto Flowering seeds. I know it shouldn't be possible but I promise these are full blown flowers, I check them everyday, watered them last night and didn't notice any until about 10 minutes ago. I'm excited and slightly freaked out.

It's a little hard to make out, easier for me but look for the hairs, on the one with the flash it's on the inside of the stipules.

Do you use a timer? Have you had them turn on and off at exactly the same times everyday? This is the only thing i can think of. GW

If they're just at the nodes im gonna say shes just maturing fully.. Are there any forming on the top s of the main bud sites?

Yes I have a timer but it has been unplugged accidentally a few times, the time it comes on and off has changed but not the hours. @Nick88 I just checked, they don't have any on the very top but on both plants the 2nd node down has pistils and my tallest has pistils on 7 nodes minus the top and the side branches have a few, there not as long as the nodes but easily identifiable, mind you this just started today or yesterday. I can't check the other 2 girls as good because they are in the very back. No B.S. here, I've never seen or heard of it before, is it possible they gave me the wrong seeds? What should I do with the light cycle?

It is normal for them to start showing sex if you have a long veg period. I wouldn't worry unless actual buds start forming. That and flower your plants soon. they are going to double, if not triple, in size

As others have stated, your plant is not flowing, but maturing is all.
