Is my plant being Macho?

I have plants in and there is two strains both strains are flowering, one type is straight flowering, but the other has flowers and little balls on it are they seeds?, is this okay why have I got balls on one lot (all from same place) and the other 2 plants (different source/place) have no balls on them. Are they still worth keeping or should I pull them out and start again?

"balls" are usually male flowers ... not seeds.
Best to get rid of any ball bearing plants unless you actually do want seeds.

Can you tell me if I should get rid of all or just the males? Will they produce anything?

Just get rid of the males.

yep dude rid the males out the room unless you want a ton of seeds

unless you are prepared and ready to handle breeding , I would get rid of the male now.

all gone, thanks everybody
