I like finishing up training by week 2 so week 3 isn’t a problem - but stay away from topping at this point.
It looks like you might have to do some supercropping (sometimes called flop the top), they don’t mind that.
I’d also spend some time on the lower structure. I like to strip bud sites from the lower half of the plant and I like to remove some lower leaves for air flow.
Cheers
