Balls or no balls????

ok so this is the first time my buddy has grown and he doesnt know if his plants are male or female yet so we're both looking and trying to figure it out. this plant has been on 12/12 for the past 6 days and now we see a bulge ontop of a shoot.

any ideas???

 

ill go to his house 2marrow and get better pics

 

everyone that said it was a female were wrong it was a male and it was chopped
