Powdered fertilizer for marijuana plants

A question from a fellow grower:

I live in Australia and its hard to get fertilizers here from out side of the country. Now I’ve read something about powdered fertilizer, is this true? Does anyone know where to get it?

There are various dry or powdered fertilizers you can get, General Hydroponics that is famous for developing its formulas with NASA hydroponics systems and has a very popular 3 part liquid also makes powdered nutrient mixes as well. You can even use miracle grow or schultz powdered water soluble fertilizer mixes, if you know what you are doing.
