It's not that hard. You get the ferts and add them to the water. Do water changes and you are fine.
And it's not that Discus are sensitive to the normal nitrate levels we keep in planted tanks it that they are sensitive to the ammonia and nitrite and DOC that normally are the precursors to nitrate.
Adding nitrate shortcuts the normal biological process.
