Yep, you over did the bone meal, blood meal and rock phosphate, 3 sources of the same thing: Phosphorus. Did you do a soil test before you added all that Phosphorus? Did you add any other nutrients to your garden?
The nice thing about well balanced commercial fertilizers is that the manufacturers took the research that says what nutrients are needed and in what quantities and put them all into one package.
The only way to know if your soil is lacking something major is with a soil test. There could be sufficient phosphorus in your soil but, for some reason, its not being utilized by the plants. Planting too early while the soil is still cold is one, incorrect soil pH would be another.
Hopefully, eventually the phosphorus will break down and not be a problem but I don't know how long that will take or if there is a way to speed it up.
