I'm not insisting that the nutes are organic, but it would be nice if there is a simple way to do it. I've also heard there's less a problem with salts when you use organics.
Calmag and "bulking agents" are a custom blend of molasses, with stuff like ferrous sulphate. (read the ingredients...either sugar cane or sugar beet origins, I believe) I use unsulphered molasses. It is not a complete set of micros and metals, but It does contain calcium, magnesium and iron, which is helpful in the flowering process. (wow...just like CalMag Plus :thumbsup
Likely a bad idea to add stuff just to prevent defeciencies, unless you yourself have experienced these defeciencies in your garden. If your nutrients are not providing your plants what they need, change nutrients. For instance, Fox Farms has all the micro's you'll need if used according to their online schedule. (no additional micronutes necessary)

Know what you're adding, and why you are adding it...before you add it.

Any and all non-organic nutrients will provide you with salt build-up. (a bunch of the nutrients are salts) Monthly flushing eliminates this problem.
