They benefit from extra water during the summer, just enough to keep the soil slightly moist, and they are very heavy feeders.
Usually feeding them will bring the color back. This article will help: https://www.gardeningknowhow.com/ornamental/flowers/hibiscus/answers-to-what-causes-hibiscus-leaves-turning-yellow.htm
