I have never used soil. This is just my o2 here. I would be checking out what other growers here using your same type of soil and nutrient combo. And see if they would not mind mentoring you. Some times having to much help can be as confusing as no help. Again. just my O2. I would enter your soil in the search box and stat checking out the links that look like they may be relevant to what you are using.
@Not2SureYet very well said, some things don’t apply to hydro that are a must in soil and vise versa
