When to Water??

[RDtrack]

I recently purchased two Dendrobiums, my first dendrobiums. One is a Dendrobium - Phalaenopsis and the other a Dendrobium - Bigibum x All Season Blue (I believe its a miniature).

Light - Currently they are blooming and I have this in a east facing window (So good morning sun, sometimes direct).

Water - I've read a lot of care sheets about these orchids and I'm confused on the watering pattern I should use. I'm use to my Phal. that I water ~1 a week, which is what I've been doing with the Dendrobiums, is this appropriate or should I stop? I've read you only water once a week or maybe twice a week when they are growing/producing their bloom stalk and then quit watering when they are blooming (only until the cane shrivels), should I follow this advice? Also I normally mist this in the morning (I don't have a humidity tray for them as of yet), is this alright or should I quit that too?

Also will the type of Dendrobiums I have loose their leaves after they bloom? Or should a new bloom stalk emerge from in between the leaves as the current ones are?

Thanks for all your help.
