AsNoriuanswered grow question 3 years ago LST and top them. Topping will stop apical root to develop and will force your plants to stay low, clear bottoms too, it will be jungles in few days and most of those small branch shoots will be sucker buds.
Use fat soft wires, do it before watering, otherwise you'll have loads of snapped branches.
Still amazing grow for 16 days !
Crazy how they develop fast at yours, very very very nice !
