good soil for autos

i need help on a good soil for autoflowering strains?? i was thinking of just going with pro-mix hp rather than ocean forest because ocean forest has to much nutrients for veg period. am i right?? should i go with promix hp then add i little grow nutes in the beginning then just go with bloom nutes after two or three weeks??l

is ocean forest ok? or is pro-mix hp better

Either one will work fine. Many prefer to grow in a medium like pro mix for the first few weeks before t'planting into FFOF.
