Answer: Your glorybower should take full sun in your mild climate, so I'm not convinced the leaves are sunburned, unless there is reflected light from a window or reflected heat from a wall. Are the affected leaves on only one side of the plant, or are they on all sides? If only one side of the tree is affected, it's probably reflected heat or sunlight. If leaves on all sides of the tree look sunburned, I'd suspect over-fertilization. Containerized plants need to be fertilized more often than those planted in the ground because they are watered more frequently. However, an over concentration of fertilizer can burn the roots because they are contained in a small area. When you fertilize, use a half-strength or quarter-strength dilution of liquid fertilizer rather than a full dose. Good luck with your glorybower tree!
