Our temps daily get to 101--our hibiscus plant is looking somewhat yellow, don't know if we are underwatering or overwatering. The leaves are more of a mottled yellow--it is blooming but the flowers are not looking healthy either. Thanks!!

If it is that warm and the hibiscus is in a pot, you really can't overwater it. Increase watering. Water at least once in the morning and once in the afternoon.
