Bit to early,
what your looking for is white wispy hairs or pistils coming out of the node sites, this will indicate it is showing female sex.
And if it looks like a male, it will have a bunch of coco shape pods coming out of the node area. they tend to be in packs vs just one.

This is my plant showing its sex, you can see the white pistils
One good thing is this. Males tend to show sex before females, and if they have been in flower for 2 weeks now like your Diary says, I think your leaning towards female at this point.
You should see signs of sex in the the coming week.
It is growing nicely though, congrats on your plant so far.
Even if it is male, you did a good job growing them out.
Best Of Luck!
