In post #18, Wash was saying you'll be Alright in topping your plant.
-Which you will since height is a problem.

I also dont see buds yet so you're still in Veg. You cant force them to bud outside (less you manually cover them each day), but cutting in veg is good, you dont want any stress once you see hairs.
-btw, that is a giant stalk! there must be some crazy wind in that spot?
