The tap water here is like 7.7 and I started using General Hydroponics pH Down (http://generalhydroponics.com/site/index.php/products/maintenance/ph_buffers/ph_down/) but I didn't realize it said to lower the pH of nutrient solution and plant fertilizers. It says nothing about just water. I was wondering if anybody has used this or maybe has some insight on to what this could do and possibly another solution to lowering the pH. Any help is appreciated.
