Ready for topping?

[adamrt]

Growing Auto Cinderella Jack outdoors to start with but will move indoors in about 30 days when the weather turns.
Should I top it? Is it ready?
Only ever topped one plant and that was by accident when the pet rabbit ate the top!
I’m new to this but do have a 4x2 grow tent.

Grower preference. I used to top my autos above 4 or 5 and remove everything under 4.
