You cannot know for sure which plants carry what.

Take viruses, for instance. Your plant may be infected, but never show the
slightest symptom of infection. Pass the virus onto another plant via a dip
and the same may not be true.

personally, I think that considering the time, labor, and cash invested into
your orchid collection, you're better off to risk "wasting" fertilizer
solution though once-through watering.

But making a fresh bucket for each plant can become a very expensive
thing.
Why not try to sort out the healthy plants from the others and soak the
good
once together and sick individualy.
I only soak my plants once when I have just repot them, and for the rest I
just poor and spray them with water (+fertilizer, insectesite,...) I do
give
them a biiiiiig shower once a year in the bathtop with fertilizer and a
lot
of water. That one time a year I water them 4 - 5 a day. And believe me
moving 200 plants op the stairs and in to the bathroom and cleaning up
afterwerds is takes a wile and drives my parents absolutely bananas.

Assume one plant is diseased. The very instant you dunk it, you have
potentially contaminated the bucket full of fertilizer solution, which
means
that any other plants dunked in the bucket can pick it up.

The issue isn't simply the bucket itself, but its contents as well.
