invision Reviewed by invision on . Cal Mag in tap water Ok so is there any reason to put cal mag in tap water. i was going to use RO water so i bought some cal mag. There is no where to buy any RO water in a reasonable distance. So i am going to start using tap water that i let sit out for 48 hours. So my question is should i still use the cal mag even though i am using cal mag? Also should i use 1 tps or 2 tps per gallon if i using fox farm grow big. As ive seen two different feeding charts...thanks guys Rating: 5
