Magnesium Toxicity?

  1. Just for fun i've been growing with tap water only. I have added no fertilizers to this plant...only good fox farm soil. I have no idea what the PH of the soil is, but the pH of the water is around 7.8 and the ppms are around 300. Is this from salt buildups? Magnesium toxicity/deficiency? 

  2. If you don't know the Ph runoff of your Fox Farm soils, then how do you know that it is "GOOD"!
