Nooo no no...get that plant out of that pot.....i dont matter if you rip a few roots you will never know....you still have a long way to go till you harvest and its gonna get ugly if you dont, they just keep growing and will end up getting root rotand it will make it impossible to flush and get proper run off and you will kick your own ass later, trust me ......get a bigger pot, wait till plants root ball feels kinda lite but not dry and wiggle that bitch out , just be easy and if you tare a few roots it wont matter, once its back in a new pot it will love you for it and keep growing and you can flower and flush with no problem....but do it asap before the roots get any bigger....ive done this same thing b4 no worries
