You need to do what is called an "LST" (Low Stress Training) By Tying the top(s) of the plant down so they are bent over (do it slowly, and bend a bit more every few days...not all at once!)

Those who have hurt you will screw eventually themselves; and if you are lucky, God will let you watch!
Through What we create- we are immortal.
