Why are the leaves on my azaleas dingy what can I do about them?

I have 2 azaleas and the leaves are not green they look like they need nitrogen or something to green them back up. The color of the leaves look dingy looking.

Azaleas are acid lovers, and you probably are seeing the typical symptoms of iron chlorosis, which acid lovers often get when the soil isn't acidic enough. use a foliar, liquid fertilizer made for acid loving plants.
