I have the same exact number of plants (well yesterday I did), 3 total, the male started showing exactly like yours looks in the second picture. I wasn't sure so I waited another 5 days, and sure enough the male flowers just started coming in everywhere, little balls hanging off of almost every branch, and right on top there was a very condensed amount of them, like 20-30. I cut him down yesterday, and didn't wanna throw it away, so hung it up side down for no apparent reason. =] I guess you can say I'm "pretend harvesting" lol, but its more me detaching from the male psychologically because its my first grow and for 6 weeks everyday I looked at him and said "I'm getting a shitload of pot from this one". Of course it had to be a male though.
So I cloned 2 from each of my other 2 plants, I only want 3 females total, so if another turned out male I'd still have the 1 female and her 2 babies. But today when I came home I saw pistils on both of the other plants!!! So I'm psyched that they definitely look like females. Now I'll just wind up killing 3 clones and keeping 1 cause I don't have the room for more than 3.
And you definitely can't do anything with the plants, not only is it a male, but its just shown its flowers. Even if males produced THC you'd still have to prob wait another 8 weeks or so, but they don't so you can either trash it or go through the gay little process I am with mine.
