Heya!

Quick question. When I add my Bio-grow nutrients to my tap water, it becomes brown. To test PH, I then use a GHE liquid test indicator. I take a vial, add some water, and some PH-test-solution, and the color changes according to what PH the water is. My question is, does the fact that the water is brown change the color of the PH-test water after I've added the solution?

My tap water is around 8.0 PH. I added 2-3 ML of nutrient to 1 L of tap water, and checked the PH. It was at 6.5. Very convenient, so I hope that is the actual PH, and not that it is just "lowered" by the fact that the water was brown to begin with.
