How much Additional Calmag for standard Nutrients

Hi,

Ive recently started growing in coco and I have a lot of advanced nutrients but that’s more for soil. I’m too cheap and too broke to buy the special “advance nutrients for coco” so how much additional calmag should I add to make my current AN nutrients safe for coco?

thanks

You may not need it if you use tap water......I rarely have to use it.

I’m using RO because I have a water softener

Thank you for the links but I’ve read them and didn’t find an answer to my question regarding coco nutes and soil nutes unless your saying I should add soil nutes then add calmag at 5ml per gallon?

I use cheap powdered nutes (Maxibloom) but I add a full dose of calmag in with it. Never have Ca++ or Mg++ issues. Yes coco.

150-200ppm cal mag is pretty standard. That's what I have been using with no problems.

I grow in coco and never use calmag. I use calcium nitrate for the nitrogen source. It has plenty of calcium. I've never had a deficiency in years of growing. I used the same thing when I was doing flood and drain and never had any deficiencies. I've never spent a dime on a calmag product in my life.
