they like the same exact things in ground as indoors. you have more leeway in the earth, though.
the thing is the nutrient content of your soil will be different than someone elses. Start small and ramp up... push boundaries and back off. take some notes for next cycle. all you can do.
i've heard dr. earth has some awesome top dress fertilizers that work well outdoors. gaia green is another, but i think they are overly expensive. find some outdoor grows on GD that list their fertilizer use and mimic those that work well.
when i grew outside i was in pots and just used my same regimen as i do inside... worked as expected. i'd add fertilizer after a rain because it was washing it out of the pots, but in the earth you don't have to worry about such a thing.
