Angraecum sesquipedale in spike - looking for advice

[radiofreekirkwood]

I purchased an Angraecum sesquipedale in late spring from a local grower just as it was losing it's last flowers. Today as the morning sun went through the leaves I saw a curious shadow that, upon closer inspection, was a new spike.

This will be my first time flowering an Angraecum sesquipedale and I wanted to see if anybody had any advice.

I'm curious if I should try to maintain current conditions exactly - if I should try keep temperatures as they are now or let it get a little cooler as the weather gets cooler. I'm curious if and at what point I should cut back what is all ready a pretty conservative fertilizing regiment. I'm also hoping that it is imperative to the development of flowers that I look at the spike constantly.
