Theses leaves have white spots on top of the leaves which are brown on the underside. What causes this and how do I correct it? The plants face north! Thanks for your help!

Hi guys, How can I counter act a heavy dose of Potash given to my Azalea's. This was the first year in many that they have finally come back and look great after much work. Someone thought they would help to make them flower longer and applied a tripal dose, which might I add was wrongly suggested by a nursery person. This was only 2 days ago and has been watered in. Can you help me save them Please
Watering deeply each time you water may help rinse the excessive potassium deeper into the soil, below the root zone.
Excessive potassium can cause iron or zinc deficiency, so if symptoms of either of these appears, provide iron or zinc fertilizer to correct the problem:

The other issue is that the pH can be raised by potash, making your acid-loving azaleas unhappy. If you suspect this, you can have a soil pH test done, then add an acidifying fertilizer if needed:

Are you able to plant cuttings from a plant? We were wondering if it would root.
Yes, you can. This article explains how:

At home I have all Azhalea Plants have Black powdery Sooty mold on Leaves and on stems and dendralions DYING DUE TO WHITE FUNGUS ON STEMS
Yes, this is a bad fungal issue. I would recommend putting, both wettable sulfur in the soil, and dolomitic lime to bring the pH back to where it should be. The wettable sulfur will kill of any infection in the soil so that it will come back healthy.

I would say, without seeing pictures, that you have a fungal infection. There are many ways to deal with this. My preferred method is wettable sulfur, and dolomitic lime. This will take care of anything growing in the soil.

My azaleas are suffering with what appears to be lichen. I have tried cutting off the affected branches but more are affected. The adjacent ash tree also has branches affected similarly but still sprouts leaves. Please advise me what to do. Photo attached.
You will be chasing your tail trying to control this. These are lichens, and will not harm your tree in any way! This article will help: https://www.gardeningknowhow.com/ornamental/fungus-lichen/treatment-tree-lichen.htm
