If you top the four new ones it will make them V off into 8 arms. Keep in mind, the more times you top the plant, the smaller the tops are gonna be. Also, when you top it, for a day or two, most of the energy is focused on repairing and creating those new arms. MODERATION IS KEY. For me, the most times i top my plant is two, because after eight top growth nodes or so, your nugs start to get really small. Good luck and i hope this helped.
