The one plant with no buds is a male and will or has most likely pollinated your female with seeds. If youre lucky enough to not find any seedn forming on the female id remove him immediately by placing a large garbage bag or something over the top of it to prevent any pollen from escaping and chop him down. Or let them go and youll have very seedy weed but will also have a ton of seeds for next season
You have 2 girls. Unfortunately Autos are bred with cannabis ruderalis, and one of your Autos Ruderalised on you ( the ruderalis gene was doninate in the plant) . Unfortunately thats one of the chances with Autos. Ive had to throw out a few because of this. As someone mentioned above, just see what you get at harvest and turn it into hash. The other girl fortunately looks gorgeous!
