Anyone help tell me what is on this tree leaf? It’s only on two leaves.

Can someone tell me what is wrong with my blue berry bush? It's been there for 30 years and use to be huge .

What is the cause of this disease or condition that has appeared on the grape vine leaves? With appreciation.

These evergreen shrubs were here when I moved in, and for the last 8 years looked great. Last year, this one had a big dead patch I clipped out, but it seems like it’s spreading. Pest? Nutrient deficiency?
First pic is the healthy color, and other pics are what it looks like when dying.

I see no active large pests on leaves. At a loss and would like to save it 😭
