LOL...wrong post...thought i was in the indoor section...i almost told you to get a fan and plug that shit in bro. sorry i cant help you out, but good luck it should fix itself over time.
You haven't said how tall, how thick the stem is, how many weeks old it is....
Outside....hmmmmm, the plant is constantly altering the leaves direction so it tracks the biggest light source available....ie Sun. Don't worry, it'll soon rectify itself, think of it as solar panels that track the Sun...
