YES SIR there is something you can do with those roots. Maybe not this time though. Next time have another female shoot on hand and graft it to your root ball and stalk. The new graft will quickly take hold of the existing roots and start to grow. Since it's already grown all the roots it will need, it can quickly begin to grow tall. I'd try grafting next time and see what happens.

I too believe one month veg is more then enough. I had this problem too when i started my first grow. I let them grow too big thinking more was better. It's not.
