Ok I mixed a litle over a teaspoon of Neptuen's Fish Fert )pictured) with a gallon of dist. water and used a ph test from my hydro setup and it came back like 3, wtf? Will this hurt my plants? Or is the test no good this way?

Thanks Much,
sorry if this is a stupid question, I looked before I asked.
