  1. guys using RO how often do you use
  2. No need, really...but every 3rd feeding or so if you must...really depends on the newts you are using...are you looking to stablize pH?
  3. Not any "cal mag" aKA EDTA... nasty stuff i would just add finely crushed egg shells into the soil, as long as you got worms they will eat the particles and it will be more available to your plants
  4. Use Botanicare Cal Mag at least once a week with waterings on my plants. Plants love them.
