Cal/mag and pH questions

  1. So everyone says the magic number for coco is 5.8. Well looking at the hydroponic scale for pH 5.8 is good for all nutrient except cal and mag. So if I keep it at 5.8 and just feed it cal/mag does the plant get the cal/mag or do I have to raise the pH when I include cal mag to my feeding?

    That has a great pH chart for both soil and hydro
  2. 5.8 is just fine.

  3. I did a little test and noticed that with certain nutes at different stages of flower my ph can go up after a day or go down so if with that particular jute mix goes up I ph it to 5.5 so by the next time I water in two days the mix should still be under 6.5
