If you are doing this outdoors, then i wouldn't do any drastic training, like bending the plant over. Spread it out is all you need to do.
Outside, it is inundated with photons from all angles, unlike artificial lighting indoors that we try to maximie with a flat canopy -- no worries about that outside. There is no different DLI being a few feet further from the sun or 10 feet for that matter on a massive plant :P
Some training to even out growth / production to avoid a massive primary cola is probably wise, but won't take much effort. Big colas are inevitably more susceptible to pathogens.
