Jimbo.... In the past I have typically used 5-1-1. This year I decided to go the easy route and try something straight out of the bag. I did a little research and people seemed to like BX Pro Mix. I started with that and added some additional perlite. Someone informed me, about half way through, that I should try Pro Mix HP. I bought a couple bales and used that on the rest of my plants. It doesn't require any additional perlite. I also add dolomitic lime, blood meal, bone meal, and Osmocote fertilizer.
