How many hours are the lights on/off. What kind of lights are you using? There is a possibility that this plant may be a male. Are their similarities on all the other plants?
Can't tell from that pic.
If it is a male it's a few weeks from becoming a problem. The balls have to open before it can spread pollin.

I saw one thanks to Tex, sometimes a plant will show some pre flowers...not always though... but it's a good indicator for female...but you really need to relax...it will all show it's self in due time.You Guys See White Pistils? :O
Update. Anyone Else? (Different Angle)
