Two things: yes they will make seeds if you leave them long enough - at the sacrifice of your buds. Two: they probably won't be viable. The plant doing this is a "last resort" tactic to insure survival of the species. You would be much better off to go ahead and take the cola, leave the rest for another week or two for those buds to fatten up, then take them. Then get some more seeds and start over, or get some clones from a friend or whatever. You can't take fresh seeds and pop them in the ground right away anyway; it takes a few months for them to die before they are viable.
