From the pictures you posted, I'm not seeing much to indicate that it's shown its sex yet. Growth characteristic does lean toward female but I'm not seeing pre-flowers in your photos just yet. Look for the white hairs coming out of the calyxes. Males have round balls and are frequently clustered. When they open, they look like a bunch of bananas prior to releasing pollen. I am also seeing what appears to be a magnesium issue in the leaves and a potential potassium issue in the stems. Can you give us a complete description of your grow including your lighting, container size, nutrients you're using and watering habits?

Back to determining sex ... How many hours of uninterrupted darkness are they getting daily?

That plant should have shown sex by now, but unless that's a they/their, I'm not seeing any flowers.

Thank you for the responses! I forgot to check back here for responses to my question. A few days after posting this I started seeing some flowers forming. All 5 of my plants turned out to be females.
