If you are transitioning your Hibiscus from indoors to outdoors, always do this gradually and start with a part sun location. Morning sunshine and shelter from the afternoon sun works also.
Your plant may have been sun scorched.
Make sure the plant is adequately watered and continue its transition to full sun.
