My two cents worth.
I guess the difference in potting medium does have some effect on the ferts used.
I personally LOVE the Espoma Citrus-Tone. I started using it about 6 months ago and saw a WORLD of difference in my trees.
I will probably get ridiculed for this, but it seems to be working for me. I spread about a Tablespoon on small pots, more on the larger, every two weeks. My plants are the best they have looked in years.
I also foliar feed Fish Emulsion and Superthive the weeks I don't use the Citrus-Tone. This may have something to do with it, but anyway I look at it, I have found a fertilizing program that is working for me.
