Caladium Postman Joyner (Caladium 'Postman Joyner') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crisping leaf margins
Low humidity or erratic watering. Raise humidity and keep soil consistently moist in growth.

Often too little light. Move to brighter indirect light to restore the deep tones.
Scorched leaf surfaces
Too much direct sun on thin leaves. Shift to dappled or bright indirect light.
Early dieback
Cold below ~18°C or natural dormancy. Keep warm; store the dormant tuber dry and warm until spring.
