how long do you expect to leave in veg, I let my go for 9 weeks. So i would wait at least 10 days and skip one node before topping again. You should wait till this plant matures before putting into flower. wait till you see alternating nodes. It really depends on how big you want your plant to get and if you have enough light to cover the footprint of the plant. I guess i said eight tops but that would be topping two more times, But if you top just once more you will have four main tops which you can bend over so the side bud sites will get more light. good luck.
