Too Many Choices?
To keep things very simple you can use Humboldt Nutrients Oneness or House & Garden 1-Component. Both can be used by themselves through your plants' full life cycle. Another recommended option for simplicity is using General Hydroponics FloraNova Grow and FloraNova Bloom. - Or - For each nutrient line that offers a Micro, Grow and Bloom, you only need to use those and you can skip the additives. Also, choosing to grow in soil instead of a soilless medium will be much more forgiving as soil has everything plants need to start.
