Droopy vanda spike and flowers

[Sammy]

Hi Guys

Merry Christmas to all!

I have a vanda that was given to me in flower, i have had it for a couple of months now and the main spike is starting to droop and the flowers too.

I am keeping it in vase culture and have been soaking it for 20 min each day in tap water and have been giving it a couple of drops of Baby Bio orchid feed once a week or so

She is in a south east facing window, getting a good amount of light, does anyone have any suggestions as to what might be happening to her or what i could do to perk her up.

Am i using the right feed for vanda vase culture?

Anyone have any helpful suggestions? Thanks all.
