pre-flowers in veg stage O.O

Hi,
umm...I dont know how did it happen.. I've been keeping it on veg stage all the time but one day I forgot to turn lights on (yea I dont have a timer) and now about 2 weeks later I noticed some preflowers there.
How is this possible?
Is this a problem?
What should I do?
Can I get some some answers please?

Thank you

oh and here is the pictures of it. Seems like a female or what?

looks female to me and i wouldn't worry plants show sex before flowering lots of time it won't hurt the plant.

It looks like its just showing its sex. If you have buds on top early that would be something different. When you leave light off for a day that shocks it into flowering.Get timer {homedepot}
