i looked at that plant and couldnt tell. if that plant is still in veg, it might not be showing yet without the aid of a good magnifier, then you have to know what your looking for. males grow balls then flowers, not buds. female buds do not start to form until you put them under a 12/12 light cycle, and even then can take a couple weeks. if your seeing pistals(which i cant see), then it is prolly a girl. give it a little more time.
