Have you tried a phosphorous fertilizer or epsom salt? A master hydrangea gardener I know told me that epsom salt is the best fertilizer for hydrangeas. You can just sprinkle a handful around the base of each plant and water like crazy to keep the soil moist and help the salt gradually continue to nourish it.
