Hi, I'm working on my first grow and a question I need help with is if Cal-Mag is needed in every watering if using RO water. My whole house is RO water and you don't want to drink, bathe in or smell my well water that out of the tap at the well shows over 1200 PPM.

If you're running LED lighting more mag will be needed.Comment
