JD my raised beds are doing GREAT. I put it in April 16th and already have Peppers, Maters, Okra starting to develop on the plants. I went with the same top soil mix you did but had read some revues online about problems so I took a bunch of Whites and Crappie carcasses and put them un the garden where I was going to plant, Then after 2 weeks I added Fish Oil Pills and the garden is going ape crazy.
I actually got the idea for the fish from reading some old Native American planting tricks where they always added a fish next to the plant to insure a harvest. I am now a firm believer in it. I don't know if its to late for you to do it but might be worth a try. Also remember to put Marigolds around the garden.
