A blueberry with iron deficiency has yellowing leaves with dark green veins, the new growth will be affected by this first.
Blueberries are unable to use the iron in soil when the soil pH is too high. Blueberries like their soil pH to be between 5.2 and 4.0 with the optimum being 4.5 to 4.8. Another problem that can cause iron chlorosis is too much water, this can happen with wet springs or irrigation that is set to water amounts that appropriate for the summer heat but not a cool spring.
