How to test pH?

  1. My water going in is 7.0 and the run off is 7.5. whats my root zone? and how can i fix this?

     
  2. your root zone ph is relative to ur runoff. you need to adjust your ph before watering in order to balance it out. i'd water with 6.0 ph water until runoff is 6.5. Depending on the age of plant, i might not flush it again until soil has dried up a bit
