Yeah, sorry man, but "little balls" = male
Seeing as you are still on a veg time schedule, these must be presex, but it's indicitive of a male plant non-the-less. I have the same situation, but my presex is female.
I just changed my timer to 12/12 to accomodate my lady's needs.
All you can do is yank it and try try again.
Maybe buy some feminized seeds to ensure a useable plant. I haven't had to resort to that as all my germs have been ladies, but I'm gonna buy some fem purple kush soon enough.
Keep on trucking brother, we need as many growers as possible.
