Wouldn't it be faster and less stressful to prun the roots back also? I used to keep a bonsai mother plant and every few months when it slowed down growth i would with hold nitrogen for a few days, take clones and then cut about a third of the root ball off and give it some fresh soil. Then I'd give it water then normal nutes the next day and it would take off again.
