First Closet Grow - Need Advice!

Growing a few plants in my closet from random seeds I acquired over the past few months. I just switched them over to the 12/12 light cycle so they can begin flowering. I'm pretty sure all of them are male except one and I am SO bummed because they are all so beautiful. Especially the one with the large, dark-green leaves. You can just rub the stalk of any of them and it smells like dank.

Okay, one picture I uploaded is showing a close-up of what looks like buds beginning to grow. Am I mistaken? These are on all of the plants.

If most of the plants are male, do I really need to destroy them?? It would break my heart, haha. And if I can keep them, do I need to separate the female from the males?

Thanks in advance for your help!!

i have trouble sexing plants but if u have males and females u gotta seperate them or u are going to get pollination which will decrease the potency of the bud u can grow out the males but they are of very little use unless u r making hemp

i was reading the growers bible and the guy in there says there is some potent males, you just have to try it < but you have to make sure the males get out of there cuz when the pollen sacks ripen they explode and pollen goes every where, so no more sensiees just seed

I wouldn't do anything yet . In pic four , I think I see female.

as soon as you know which plants are male and female separate them.
if you allow them to fully flower in the same proximity, the males will eventually pollinate your female plants,
-pollinated females make for weed with lots of seeds (ugh)
-if a female plant is left un-pollinated for the remainder of the flowering stage, she will begin to put all of her energy and nutrients into producing hairs saturated in wonderful THC (good stuff)
so basically, if you want weed without seeds and more "good stuff" keep the boys away from her

@ Dadio - Yeah, pic four is the female. The rest have little seed nodes. But what is that in pic three? Are those buds growing or what?
