EWC tea will definitely keep your soil microbiology nice and healthy even if you are using chem ferts. If you can get ahold of EWC you can probably get a hold of some powdered sea kelp, bat guano, and molasses. Those 4 items can provide you with organic nutrients so you don't have to use chem, unless you want to use chem witch is your choice.

You can even go out and purchase beneficial bacteria and fungi strains that do well in high salt(mineral) environments like General Hydro sub culture M and B, or Plants success great white.

But yes EWC tea is an excellent idea to keep your micro heard healthy and diverse.
