Nutes Question??

In my grow, I will be using Pure Blend Pro nutrients. I bought the grow, bloom, and some calmag. I got a free bottle of Liquid Karma with my purchase.

Question is:

Will i need to use the Calmag if i have the Liquid Karma or vice versa? And could i use them both?

check the ingredients or guaranteed analysis if you can find it, they have em online too. most veg nutes pack enough cal/mag but sometime nute companies purposely leave it out so you also have to buy a liter of cal/mag. a good trick to get cheap calcium is to compost egg shells or add milk to your compost. or add a teaspoon of milk to your water, and a pinch of epsom salt for magnesium.

Ima check up on that, thanks
