I totally get it, @Bandwidth. For being such a large player in the nutrient game, Advanced Nutrients website, calculators and Bud Labs tool are not beginner-friendly at all. The answers aren’t there for someone without experience. I have found that my local hydroponics store and the people here are the best resources to get this stuff figured out right the first time.
FYI, there is a nutrients section on this bulletin board. It can be found here:

For what it’s worth, I am also growing in Fox Farms Ocean Forest soil. Following advice given here(based on that soil), I have not added any nutrients until the plants reached the flowering stage. I went to my local store today and purchased Advanced Nutrients pHPerfect Bloom, parts A & B. I will be trying it out tomorrow evening for the first time.
In case you are interested, I will be logging notes in my Grow Journal, which can be found here:
