That’s the beauty of growing! It’s up to you!
That said, is the plant a photoperiod or auto?
If auto, maybe just bend her over from the top and do LST. As new growths shoot up, you’ll want to keep pulling the plant down. That’ll lead to them bushing out, and multiple bud sites like a couple pics I attached.
if it’s a photo, you have more wiggle room because you can essentially “pause” the plant in veg until you’re ready to flower. So if you decide to top the plant and it stresses it out you have the luxury to let it recover before initiating flowering.
