It is, more than likely, a nutrient problem. What kind of nutrients, or soil do you use? Blueberries cannot thrive in most soils fertilized with ammonium nitrate. Instead, they rely on ammonium sulfate for their nitrogen. This can also be caused by the soil being too alkaline. The correct fertilizer and soil will compensate, and make the soil acidic for them.

I used half potting soil and half compost with coffee grounds.
