See how the larger roots started to make circles? It means they're searching for an area to grow. Personally I would've transferred a 7-10 days ago but I know some people prefer to let it sit so it doesn't root bound the next pot before flowering. All depends on your schedule
Well I repotted 3 of my 10 plants. 1 of each strain. This one though, was the only auto so i'm afraid a killed about 1 week of its veg cycle, hopefully it will produce some decent clones as it is my only northern lights.
You can't take clones from an auto though? You should have put the auto in a pot that it would stay in its whole life, the less stress the better when it comes to autos.
