Flowering during veg??

Hi i have planted white widow seeds, which i have received as feminized regular seeds.
I am in 7th week after seed, keeping a 18/6 light schedule.
I am growing with dual spectrum HPS lights.
Weirdly after 6weeks it seems like they are entering flowering.
You can see the pictures below that flowers seem to appear. Is it possible that they sold me auto strain instead of regular??
Somebody please help since i am 99% confused at the moment

Pretty sure they are autos. You should probably start flowering nutes

Damn. Such a bad luck.
I was giving them Veg nutes until 2days ago. I also did some topping.
You never know with unreliable seed suppliers.
Somebody else can confirm that its auto flowering?

I would say there is a 99% chance those are autos 1% chance weird strain that flowers under 18/6. They look happy i wouldn't worry about feeding them veg nutes until now, thats how a lot of growers do it, start flower nutes now.

If you did not change the lighting routine, then they are auto's
