They are hydroponic nutrients, regular fertilizer can't be used for hydroponics. They are mixed in with the water according to the instructions on the package. Just make sure to add nutrients whenever the water needs to be refilled!
If you are growing them for propogating into soil then as soon as you see little roots and make sure to water well so they can adjust, however this video is about growing pothos in water forever so they don't need soil! As long as there is enough light and fertilizer they should be able to grow in water.
