looking good. Get them out of those cups and into some 3 gal pots.Then Watch them explode !! Also , start foliar feeding. (spraying the plant) with nutrients. It will help a lot ! make sure you spray when the lights are off. You can also "top" those fuckers for 4 main colas instead of one. there is a very good thread called , " topping for 4 main colas " created by "Uncle Ben" you should check it out. Could def. help your yield !
