6.45 is too high?

From most of my research (videos, forums, etc) it said 6.3 - 6.9 PH range is what your aiming for with a soil based grow, is that not correct?

Yeah the PPM is fine. As long as you have a good filter and replace it when your suppose to, you dont get a mineral build up.

Bacteria in the water? Nah, not where I live, this stuff tastes better then bottled water.
