is the one on the left the autoflowering strain?

i germnated 2 seeds 1 was feminized and the other was autoflowering, the plant on the left looks like it's starting to show bud sites so would I be correct that the plant on the left is the autoflowering one since i am still on 18/6?

also how do the plants look?

Yes

You have crunchy leaves in the background and some leaf curl.
