You, my friend, have had a hermie pop up... Your crop is probably partially pollenated, but I would still try to remove(carefully) the lone(hopefully) male flower, and hope there aren't more... #1-U used bagseed, which is NOT always a bad thing, I KNOW(some of my best findings came from like one or two nice seeds I have found in different eighths of awesome nugs), #2-U probably got a lil too curious, as do most new growers, and looked at them while they were in darkness, thusly interupting their sleep cycle, stressing them, and causing a hermie to pop up, or #3-Most likely, it may just be an unstable, and finicky strain, that was just some commercially produced schwag, which I have seen awesome kind buds grown from, but usually this is not the case... I'd most certainly try my best to get ahold of some good genetics, and watch those light leaks, no matter how tempting it may be to look at them at night(if u have to, get a green led head lamp, and make sure u r in total darkness before approaching, and u can see them under a green spectrum, which they won't recognize, and it will not disturb them)...
