No, you don't have a problem. When they start to show their sex you can get rid of the males and just put the females back on 24 hour light to vegg them some more. When people vegg for just 3 weeks that is usually from a clone not from seed. If you flower those out from where they are now you will be doing good to get 7 grams of dried buds from each one. If that is all you want to do then by all means keep them going on 12/12 from this point. If not then you should vegg them a bit more after they are sexed. Just keep a good eye on them and watch for signs of their sex and you will be on top of getting them back into vegg so that you can have a nice harvest. I think that you could pull an ounce each from that setup.
Oh yea, you can also take clones after the females have vegged a bit more. That way you will get some decent sized clones to get started for the next grow.
