Questions about fertilizing Phalaenopsis

[HiOrcDen]

I'm planning to fertilize my orchids for the first time, and I've got a few questions...

If the medium is relatively moist, is it still necessary to water thoroughly before applying fertilizer?

If I should always water before applying fertilizer, should I fertilize on the watering schedule; that is, if say I'm fertilizing every two weeks, is it ok to fertilize approximately every two weeks on the closest day of watering?

Once I've mixed the fertilizer solution with water, how much do I apply to the orchid? Do I just pour it in until it starts to drain out the bottom, or more thoroughly? (Strange that I haven't seen this question addressed in any tutorial lol)

Sorry for so many questions...
And thanks in advance
