Answer

The NYBG orchid curator says it's best to use a balanced fertilizer such as 20-20-20 in powder form to supply all the primary nutrients needed for flowering plants.

These numbers--NPK numbers--represent nitrogen, phosphorous, and potassium.  N (nitrogen) helps with vigorous growth and dark green color. P (phosphorus) promotes root development and flowering. K (potassium) is  for overall hardiness and disease resistance. There are also secondary nutrients and trace nutrients.

Some orchid growers use high-nitrogen fertilizers such as 30-10-10 to grow more leaves and then change over to a balanced one. Of course, it’s easier to simply use the balanced formula, but the high-nitrogen  method works is if you remember to change over well before spring bloom period. 

The American Orchid Society provides general fertilizing tips and weekly fertilizing recommendations.

Note: Remember that chemical fertilizers contain salts that can build up over time, possibly burning the tips of leaves. Leach out these salts by occasionally watering with plain water.
