I'm not sure how long till you'll see signs of sex or bud. But something I'd suggest.......
Get her out of that cup. I'd be surprised if she wasn't already out of room for her roots, plus see through cups are no good once the roots show around the edges. Light harms roots. Plant her in something bigger and not see through. Also since you flowered before maturity she'll multiply in size a little more during flower.
A 3 gallon pot should be plenty big enough.
