  1. so here is my question.....
     
    using tap water... at 350ppm... 
     
    and nutrients....
     
    lets say I want a PPM of 900... for this would I add nutrient untill i see PPM of 900 total nutes + water.....
     
    OR
     
    do i take 350PPM and add 900 for an overall 1250ppm?
     
    just a basic question... I have been doing the lesser 

     
  2. If your tap water is that high, you need some new water.

    You want a total of 900 after nutes.
