EDIT: Just went to the Epsoma link posted above, and they were individual additives (which I like). However, what I'm talking about below is their pre-mixed fert/nutes bags. They have them for Flower, Tomato, Citrus, Holly, etc. Read the bags to see what each mix contains.
One of my local nurseries carries Epsoma natural ferts. $8-10 per five pound bags. I picked up their Flower, Citrus, and General 5-5-5. I got the citrus because I liked some of the added micro and trace elements they had, so I mixed a little into the soil. I went to Home Depot the same day for peat moss, and saw they were selling Epsoma as well, for about the same price. So there's a good chance you could hit one up and get some pre-mixed organic ferts on the cheapish. I don't think any of the bags listed Kelp in their ingredients, though, so I'm going to pick some of that up from the nursery. I haven't found worm castings yet. I read somewhere they sell them at Wal Mart now, but this time of year their garden section is stripped bare most places. Many mix recipes say mushroom compost can be substituted, but I'd consider that a last resort (I like shroom compost though, so that's in my soil mix no matter what). There's another thread about best beneficials, and Kid Twist posted a link to some mych product that looks pretty sweet and is only around $16 from amazon. Seems like a good cheaper alternative to
Great White.
My soil is cooking now, so I don't actually know how well the Epsoma pre-mixes will work. This is my first organic grow coming up, so I'm certainly no expert, just throwing out some of the products I've stumbled on to.
