What's good Doc? Alright so I set up a few pics to try and help you determine what the sex of your plants might be.
First off here is a shot of a female preflower. If the img. is too small I can try and resize it. They're not the best imgs. but they'll probably do the trick.
That white colored hair pointing up in the box is the female preflower coming out of the pistillate calyx. And that off shoot to the right of the preflower is called a stipule. Don't confuse that with a female preflower like some do.
Now here is a shot of male preflowers.
Now you can clearly see a "cluster" of
staminate calyx's. This is a male and I tossed this S.O.B. as soon as I spotted the male flowers.
Now as far as those "bananas" you mentioned, those would be male flowers appearing on a hermaphrodite. My Skywalker just turned hermi on me a few days ago but I don't have imgs. on that yet. But those are easily identifiable and I wouldn't worry about it until you start flowering.
