Adding vinegar to rain water for blueberries

Wondering if anyone adds vinegar to rain water for their blueberries and if so how much? I found a lot of recommended amounts for tap water but not rain water. I just watered mine with 1/4 cup to 4 gallons. My cheap pH kit said less than 4.5 (red) the color turned pink. I decided to ignore the now I'm kicking myself. My kit also says the plain rain water is 5.5, I've tested with an accurate meter and know it's 7.0...
