First time topping

First pinch off I like to have 2 good sets of nodes so it turns into 4 stalks

With photoperiods you can do it as long as the plant says in vegetative stage, do it one time then wait for the plant to recover and then do it again, keep in mind that every time you do it you lengthen the growth for 1 week.

How much room you got and how big you want em? Topping makes em bushier and wider but if you got the height then you want them bushy, wide and a bit taller.. if your tent is smaller then top em now. I wait til 5th or even 6th node to top.. and remove the bottom set of branches as they yield shit anyways/ get in my way, but I grow under lights in a room not a tent so have the height to grow monsters.

Plant looks strong and healthy ,you can top right now even more time while in veg ,after 3rd node and then let her grow and top again 👍🏼.

Hola si tu idea es hacer varias podas apicales (multi-topping) te recomiendo cuanto mas temprano mejor, ya que se logran plantas mucho mas robustas cuando la planta no gano muchos cm de altura, y en tu caso claramente se observa una distancia internodal, con lo cual si fueran mias, cortaria mañana, espero que te haya servido, en mis diarios tengo una Frisian Dew que sufrios mas de 15 podas apicales, puedes pasar a verlas si te interesa, saludos desde Argentina.💪

I would do one now, their healthy enough
