Please help before I kill my new plant

[nynighthawk]

Howdy,

I recently bought a Maxillaria Tenuifolia on eBay. It arrived last Wednesday in good condition with about seven flowers in bloom. The plant looked a little dry from its travels, so I gave it a little water, with very dilute fertilizer and put it in my plant room...moderate light. The plant looked great for a couple of days, but by today-Sunday- all the flowers have turned dark, soft brown and some have started to wither. The leaves all still look fine.

Whaaaa happened? Did I do something terrible by giving it a drink? It was not standing in water or anything, just enough water to run out of the bottom a bit.

Could the plant have gotten overheated in its shipping box and resulted in all the flowers disintegrating this way?

The plant is in a mix of bark chips and spongey rock (like small chunks of pearlite). It's in a 4" pot.

Is there something I should/should not do at this point?

I know that once a plant is damaged, there's a "lag time" before symptoms show up and then it takes a really long time to turn things around, so I'm hoping that you can give me a little guidance on this. I'm a newbie with this plant and don't want to kill it. It's a great looking plant.

Yikes!
