Magnesium defiency.

Hi guys just a quick one, on my first grow and I've developed magnesium defiency. I'm growing in coco now I've just read some were I should of been using cal/mag through out the grow? It's now in the post. How do I add it to canna coco nutrients. I make my feeds on a daily basis not using a res or anything just hand fed. All I no is it effects the EC of the feed, does this mean I'd need to lower the dose I feed my plants? Thanks guys and hello I'm a newbie currently on my first grow.

Yes, in a coco grow, you should be feeding Ca and Mg regularly. And by doing so, the addition of CaNi, CalMag or Mg (Epsom) will affect your EC. So add slightly less base nutrients so the addition of the CalMag or whatever you choose to use, will make up that difference in your EC. Good luck.

I usually just add a tspn of calmag per gallon of water.
