The super cali is teaching me a lot about def. This thing is still a little mag def and it's crazy how close the tips look to nutrient burn.

RO Water, learning the correct CalMag Add. I just bought a new Cal Mag. the Botanicare has 2%N as well, so I looked around and found the GH CaMg thats JUST this so I'm excited to use it.
