When should I top this plant?

Hello all…this is my first time growing indoors and only my second grow…I grew 2 on my deck last year…I currently have 3 plants …a purple train wreck which is a bag seed, a critical cheese which came from a friend who grows and a sour diesel from ilgm…the ptw is 35 days old and wondering if I should top it yet?
