Distilled water and CalMag

Discussion in 'First Time Marijuana Growers' started by love2trip, Nov 22, 2011.

  1. Hey guys so I've been having CalMag issues throughout my grow using roots organics soil and watering with only distilled water. I did a little research and I read that people using RO and distilled water often have to supplement CalMag into their water because RO and distilled lack it unlike tap water for example. So my question is how often should I add CalMag into my water? Every watering, every other watering, etc?? Also, how much should I use?

    Thanks in advanced,

  2. i use cal mag every other feeding, so like once a week.
    1 tsp/gal

    you may want to use more as your plants seem to need it, I use it as a "just incase."
  3. Thanks for the quick reply mate. I'll take it light for now seeing as I just had to flush from over ferting with grow big.
