Wonder where you got them ideas dutch lol. Yo make sure you get vermiculite too. Perlite makes the soil extremely airy and light and vermiculite has the same concept but it works a lot better for water retention. Yea vics super soil is the shit but its a pain in the ass to make. Dolomite lime is good, epsom salt is good. If you can find it mycorrhizae fungi is a great addition to any soil, it kinda syncs up with the roots and makes it a lot easier for them to absorb nutrients. But basically anything in vics super soil is gonna be good. Theres something else called azomite which ive heard of but never tried. Mix in molasses when you water/feed your plants.
Oh and make sure you get plenty of that meatmoss its Dutch's favorite.
