When I'm shooting for a certain ppm goal/target, should I exclude the ppm reading from the tap water?
That's not a stupid question but one I am not sure I can give the best advice for, especially scene I have never used one. The problem here is that you don't know what elements are in the fresh water that are giving you the reading anyway. Even if you did how would you compensate for it in your nutrients because it's a pre formulated mix? The best advice I have is to mix the nutrients to the manufactures directions (2 tsp per gallon etc.) then take a reading, and use that as your base reading.
