This website says that "Normal (urine) pH levels should be in the range of 4.0 to 9.0"
Neutral pH is 7.0 so your reading of 6.5 is slightly acidic, assuming the test strip you used is accurate. Using an inexpensive calibrated pH meter should provide a more accurate reading compared to pH test strips.
Diet can affect the pH of urine, which can change throughout the day.
