I don't know for sure what visual traits autoflower plants posses, but if it's not one, it looks more like a sativa dominant plant. From those photos I can't see any indication that the plant is flowering. It looks like one of my normal female plants, except more like a sativa than mine. Just guessing, but if not a ruderalis then it's maybe 75% sativa.

You'll probably want a bigger container soon, but other than that I don't see anything wrong. (That doesn't necessarily mean nothing's wrong.) I don't see flowers or preflowers. Can you put your camera on macro, hold it real still (tripod?), and get real close to what you are concerned about? Preflowers are a little pod about 1/8 inch in diameter. The grow right in the crease where a new branch comes out of the main stem. Considering the size of the plant, you should be able to sex it using preflowers. Carefully open the outer layer of the pod and look inside with a magnifying glass. If there are hairs, she's a female. If there are balls, he's a male.
