I do my seeds the same as Michele. One other brand of fertilizer I used for the first time this fall is made by SunnyLand out of south Florida. I wanted to try a slow release on the baby seedlings along with the water soluble I use weekly. I found a 10-5-5 50# bags for $29 This has no fillers, like sand or gravel, it's all fertilizer. It also has milorganite in it which helps keep the rabbits out.
