2.5-3wks is usually when it stops. Should see pistols spiking out instead of new nodes and leafs like now still. Some strains continue to gain height for another couple weeks if its very sativa influenced.
Structure looks good I tried to make something similar with the net just to fasten every cola in place. Id defol pretty good and keep it spacy between colas.
It might get a little bigger than intended as you got a good week to go but Id shave the leg area and try to keep it the way you intended. If anything just raise the top net in a couple weeks maybe the bottom as well to catch the lower colas from toppling over.
