How old? Photo I am guessing? Maybe a few more photos of some other potential node sites could be helpful. In my experience longer periods of not showing signs are more female traits but that is not supported by any science, just personal experience. Males will look like little balls and sometimes form in clusters, a female will show a calyx and have 1 or 2 white pistils coming out from it that will look like little white hairs. Hope this helps and best of luck!
