Hey, if you use Fox-Farms products, try mixxing your soil with the "light warrior" seedling mix. It contains the very mycorrizae you are looking for. I ran out and read the bag, and it supposedly contains bacteria that helps your other nutrients absorb into the plant (chelate). Subcool recommends 2 parts ocean forest to 1 part light warrior, to lighten up the mixture, and cool off the sometimes hot ocean forest. It works very well and takes the plants all the way.
