They appear to have been overwatered. It looks like they are in a container, within a container. This will not allow to drainage, and therefore not allow proper evaporation.
You will have to allow them dry out fully between waterings. A moisture meter can help if you don't have a way to lift the containers to check the differences in wet and dry weight.
a teaspoon of WETTABLE SULFUR and a HANDFUL of DOLOMITIC LIME per container will help, or a fungicide such as one at this link: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
You will also want to fertilize them with an appropriate fertilizer for blueberries once they recover. They are sensitive to nitrates, so ammonium sulfate is more appropriate. This article will help: https://www.gardeningknowhow.com/edible/fruits/blueberries/blueberry-fertilizer.htm
