Welp I’ll bet dollars to nugs that the sun sets in the direction the plant is leaning.

A gentle breeze. As plants move it the wind the back and forth action exercises the stems cells causing them to strengthen. After 24-48 hours of a light, wafting, breeze and it will perk right up. Sometimes if the light isn't intense enough, the stem will elongate, causing the plant to tip. The most important thing is that the stem doesn't come in contact with, ie lay across wet dirt, it will dampen off and die.
