looks like neither to me...just the little nubby thing that grows near the nodes. a female will look like a while hair and a male will look like a roundish ball shape
It's most definitely a female. If it were that size and you don't see any pollen sacs developed anywhere, she's a girl. They generally show sex at around 2 months of age during veg if you know how to tell. Probably the best way to tell is when you see those pollen sacs start forming. They're easier to figure out than the pistil. LOL The very first pic you posted is a nice example of the pistil on a female plant. TWW
