You can use most fertilizer.
I use osmocote slow release pellets mixed through the soil and every 2 weeks I use a liquid fertilizer (I have a few that I use on rotation - osmocote all purpose, amgrow nitrosol & Charlie carp organic)
I also use seasol every other week.
Check the NPK ratings and maybe read about what each of them mean and what they do for your tree.
N = nitrogen (shoots) P = phosphorus (roots) K = potassium (flowers and fruits)
Remember to stick to the guidelines for frequency and dose.

Any fert will do as Ben has already said. The Hortico one you have listed has all the required elements and includes Trace Elements so it will be fine.
