Its probably a day or two too early to tell yet. That little pecker stickin out will slightly change shape and either get more round, or more like a sharper tear drop. I'm gonna call female on that thing though, that's what it looks like to me, at least from looking at the little nub on the right side of the stem. The one on the left is a little bit concerning but its young, so who knows. I notice a couple other factors from your plants that have me thinking its a female, but I'll keep those to myself because I am researching it myself in hopes of being able to accurately identify females earlier. Once I know I am right I will post a thread explaining it in detail, if I am wrong then.. at least nobody knows so nobody can tell me I'm wrong hahaha.

Anyways, just putting it out there that I am calling yours a female, please make sure you let me know in a few days if I was right or wrong. I would love it know.
