[Bud]

I am sorry you had four spikes and all of the buds blasted...it would of given you a magnificent set of blooms...
you are giving it the correct culture.IDK why it blasted... in fact in Yokohama this kind of Neo is grown outdoors mounted on a peach tree and winter can be 32F for 3 months in that area...
in fact you should water it if about to bloom and Neos are not supposed to dry up, its supposed to be moist but not wet...
if near a door and left open the draft will dry the buds...
or did you wet the buds and let it get soaked in cold water? and also we are not supposed to use fertilizer when orchids are in bloom... maybe the chemicals blasted it, I dont know...also humidity issue if you moved its position while in spike...
hope springs eternal; the next time it will bring you more spikes and blooms...cut the blasted spikes to send signal to the plant that it is in growth mode so it will spike again
