Well there are a couple things you could do depending on what you want to do lol. The first option would be to cut just the main stem where the red line i made is. This would encourage all the places where leaves are growing out of the stem to grow new grow tips (branches).
The second option is a little more advanced and depends on if you want to grow more after this plant or not. The plan would be to cut the main stem at the lower yellow line i made just above the fan leaves without cutting the little leaves growing out the sides. The plant would respond the same as in the first option but you would also be able to use the top of the plant to clone.
The benefit to this would be that you would have an exact genetic copy of the first plant so when you decide to flower your plant and if it becomes female, you can keep the clone in veg and grow that one for the next grow around, and you will be sure to have a female.
Cloning is not that hard and you could probably pull it off if you do some research. There are a lot of different methods so you could probably find one that works for you. In my experiance clones are much healthier than seedlings also and you can flower them at anytime because they are sexually mature. The other two yellow lines i made are only if you want to clone the plant. If your interested in this route i could try to help you with it.
