Pollination problem. Need help of experienced growers.

Hey y'all,

So I have a pollination question. I have 36 girls they are all about 4 weeks into veg. They're giving off preflowers. There are single full grown calyxes growing at the internodes on the plants. This is my second grow I'm not sure if this is normal for pre flowering. Either way there are orange colored stigmas coming out of them. When I break open the calyxes there are little tiny things that look like seeds forming at the end of the stigma.
All of the older calyxes have the darkened stigmas and the little balls inside. The new growth has light green colored stigmas. I have not looked inside for the little balls.

I have checked for male preflowers and haven't found any at all.

I was reading on another thread after finding a picture on Google that looks like what I have going on. On that thread someone said that it was just an ovule and not to worry about it. I can post pictures tomorrow.

So in the end I'm wondering:

Is it possible that one of the plants I had in my greenhouse grow that hermaphrodited pollinated these girls in my indoor grow?
The grow is about 100 feet away from the greenhouse one. The last plant was taken out a little over a week ago. The girls have been pre flowering since I got them. Looks like the cloner that I got them from took them off of a plant that was starting to flower.

My second question is: are the little balls just ovules?

Yeah, actually each flower has a tiny little seedlike thing in it, they just don't grow into seeds unless pollinated. If you dry buds out in a microwave and they get hot enough you can hear the seedlets crackling like tiny popcorn. The flowers at the nodes will normally be larger than the later ones just because they're the oldest.

You could have carried pollen in on your self

You may have accidently pollinated the girls

100 ft is nothing to a canna sperm 10 miles maybe?

continue to grow them out

removing the pollinated plants as you find them

but a pic would be nice

Good Luck
