Do I have an autoflower growing? HELP.

I got 3 free seeds when i order my blue widow seeds. The bag was marked ER2 that the freebies came in. I assumed it was easyryder2 BUT, The site I ordered from only has "Easy sativa". The description for this doesn't say anything about autoflower and, that it does not do weel indoors. The funny thing? One of them is ten inches across and five inches high!!!! Also has pistils already and it's 20 days old today. Should I put this one into flower now or wait? From what I understand, the ER2 strain is a mix between lowryder2 and ak47 and can be autoflowering. My issue is this; The bag these were in was marked ER2 fem but, the site sells what they call easy sativa, no ER2. Any advice?

Stay on the safe side and leave it with the veg, as an auto will grow with whatever light you give it. if she starts flowering without changing light times then you know you got an auto


P.S someone correct me if im wrong

That was my first thought on this. Then, being new, I thought, "I better get that under a hps light soon." Lol.
