VERY NOOBIE, need help with a Orchid

[BryanAndSamara]

Okay, I feel like the guy walking into a bar for the first time. Everyone else looks at you like you don't belong, and you order your first beer by saying "I'll have a beer".

The Bartender glances over his shoulder at the 120 varieties on tap and then stares you down like a moron.

That said.

I bought my wife 2 orchid plants for Valentine's Day and our Anniversary (both about 1 week apart).

One was delivered large and blooming, a truly beautiful plant.

The OTHER however, was small and budding, with a few open buds. Also, gorgeous. We sat and stared at these things for about an hour, just entranced by the delicate beauty. ( I see the potential for addicion)

Now, about 2 weeks later, the big one is hale and hearty, and looking good.

The small one, however dropped a couple of buds, and now has a leaf turing brown.

Please advise on what potential problems with the small may be and what I can look into.

I am not looking for you to solve my problems, but some diagnostic hints in the right direction would be nice! ;-)

Thanks!
