I was gonna ask what your humidity was. The leaves have some rippling going on, which is usually a sign of the plant cells swelling because they can't get rid of some of the moisture. Your humidity isn't crazy high, but it is a little higher than you'd like.
It doesn't look like she is showing sex yet. It's hard to tell from the picture, but all I see is nodal formations and stipules. When it starts to show sex you will see a calyx with two tiny white hairs (pistils) emerging. If it is male you will start to see multiple calyx like balls form. Your auto should be female, but your mystery plant could be either. Mystery shouldn't really show until you switch lighting to 12/12, and if it is a male, you want to get rid of it ASAP so it doesn't pollinate your JH
