I am new to the forum and new to caring for azaleas. I moved into this home last winter and we have many established azaleas in our yard. I have noticed over the past month or more that they seem to be yellowing and do not look healthy. I am attaching photos to help with a potential diagnosis. I would appreciate your thoughts on issues and remedies. Thanks

Did you feed all those azaleas last spring?

Look under the leaves, you might find insects or evidence there.
Azaleas are tough; while they may not look their best, they will live for decades with no special care. Now I'll step aside for others with more specific advice.

What is so weird is that they are all looking the same but they are in different areas of my yard..

I agree with Sally, look closely at the leaf undersides you more than likely have spider mites. There are horticultural oils and systemic insect killers to control mites.

I have examined the leaves and there is black stuff on the bottoms of most leaves. From reading info would that be lace bugs? If so what is the best way for me to get things under control? I have 2 really large azaleas that I do not want to lose. Thanks

Try a horticultural soap spray above and below the leaves. And add some holly tree acidic powder around them to the leave's edges. They like slightly acidic soil.
