Looking like avigor growing plant,, whay not topping=?
but i think your light is to clse to the plant// to strong, because she grows with ashort internodial distance.... rise the light// dimm it and she will grow with more internodial distance
then training is much easier on her
Topping on photoperiod plants is always a good idea who wouldn't want more shoots, more shoots equal more colas which mean more bud. Hopefully, I answered your question and remember Happy Growing and Free your mind one puff at a time.
I'm topping this week just waiting for sterile wipes for my scissors haha, I'm using the light at 24 inches which is mars hydro recommended distance I will try higher the light just don't want a huge stretch haha
