I am not too sure how nilocg packages his chemicals, but I would assume they would be packaged individually so that you could mix them to whatever final concentration you want.
In terms of dosing, PPS-Pro will be fine for your RCS. You could even go EI, and there would be no harm.
Regarding the second point, you may be able to get away with every other day fertilization if you are using PPS-Pro, but you may not be able to. It depends on how much lighting you have.
PPS-Pro works on the basis that you are adding "just enough" fertilizers for the plants to use up on a daily basis; increasing dosage and skipping days would work, but obviously, you cannot take this to an extreme (dose an entire week's worth at once, for example).
