Does Peters citrus fert comes in larger quantities than what is offered on Amazon?
Jack's 20-20-20 seems like a good fert.Do you know a source you are using with a decent price.

You better take Jack's Professional 25-5-15, it,s better for citrus

Last year i used Foilage Pro,9-3-6 in combo with Fish/kelp works great too.
I hope that i do not need anything else.Soil contains small pine bark,cedar mulch,turface, perlite.

All Peters fertilizers can be purchased in 25-lb. bags. I purchase Peters 25-5-15 W/TM in 25-lb. bags. The value of the formula 25-5-15 is that it is a 5-1-3 ratio, which is the ratio that citrus roots absorb nutrients from the soil. - Millet
