V Pak Chong spike / bud drying up? help!

[stefpix]

Hi
I have a Vanda Pak Ching. the little spike grew to a vouple of inches but now it looks like it is drying up...

I wonder what would be the cause.
It hangs on a southern window gets good sun a few hours a day - supplemented with CFL.

It is growing new roots and those look good.
I wonder if the humidity drop caused this.
In the summer I had 60 % or more now just 30/40%. should I mist more in the future? isn't it bad to mist in between leaves?
for this may be too late but in the future?

thanks

ps but at least my Spathoglotthis plicata's spike seems getting on the way to the finish line! and the Phal equestris' too

Maybe it got too cold? Vandas don't like the cold. The humidity should be okay as long as you are watering on a regular basis. Watering in between the leaves is okay as long as it is done early in the day so they have time to dry out before nightfall.

Thanks
but it is in my bedroom so the temp is always at least 67 F so should be ok...
i got it a couple of months ago so is it maybe adjusting? the new roots are growing at a visible pace...
so should not be unhappy.
