Hi there.

Looks male to me due to what appears like clusters of balls in the second pic at the pair of nodes next to the stem, 2 from the top.

If you can get a closer pic of that area it would help greatly but see what others say.

You say they were feminized seeds?
I have read that they are born from hermaphrodite plants and therefore will produce hermie plants which is what could be the case here.

If it is female, by now you should be seeing enough pairs of small white hairs at the node interludes to be confident of her sex.
