"supercrop" technique. Break, gently (hahah), then tape up damage to bake a severe bend in trunk (apical meristem). itill heal and form a nice thick knuckle. Do watch for any nanners in 2-3 weeks. Google it for lots of anecdotal experiences.
don't want to snap it.. want minimal damage possible during process.. weakinging stem (~pinching) before bending it can help. Doesn't have to be 90degrees, but does need to get it down under light... maybe lower on branch can reduce angle, but also consider how much of the plant you are impacting. anyway, tape it up after, even a little support might be needed. (tie to ceiling or prop up from below with long bamboo stake etc etc)
The pale spots are light damge... it will get worse.. leaves will turn pale - like an albino plant. bud will turn white too at some point. It doesn't 'spread' - just caused by way too many photons of light.
