Cocos A & B - Help needed

[GpsFrontier]

Generally you'll want to change your nutrient solution every week or two. I'm not familiar with the nutrient your using, so can you post a link to the calculator?

But I did do a search for the product to see what it was and one website states this about it:

"Coco coir requires an extremely precise composition of the various minerals, a task that you can safely leave to Cocos A & B."

This is simply a bogus claim, coco coir dosen't require a different nutrient solution than other hydroponic growing medias.
