Sure i guess so...but your poor plant has JUST entered veg stage. Even if you start 12/12 now you won't see sex for up to 4 weeks...top your plant and then concentrate on the sides with some LST (low stress training). A plant that is allowed to enter preflower stage will give you better results. With all that extra time you spend growing it in veg stage will only increase your yield...and that's what we all want.
