Too much water or over-fertilized? Too much sun? Have they done this before? Pests? Could be a lot of things causing it. Check with your local garden center or county extension service for advice.
Your dirt ph is off. Blueberry plants need an acidic soil.
The nutritional or environmental cause of lightening and yellowing of blueberry leaves is called chlorosis, which is the lack of chlorophyll in the plant. There are several factors that can cause chlorosis---compact or damaged roots, poor drainage or a high pH level in the soil which blocks the plant's ability to take up the needed nutrients. The blueberry stunt virus is spread from plant to plant by the leafhopper pest.
Linda is right, they need acid. You can purchase some at any garden center, apply as directed. That will get them through this season. I use oak leaves and pine needles to mulch them, both are acidic and I have not had to treat with a chemical since I started this practice.
To much water probly.
