UKCat and Rosie, yeah, that's kind of what I thought too. It doesn't *look* like a sick plant. I think I just got freaked out and paranoid because I lost about 7 leaves to the yellowing and dying off all in the course of about 2 weeks. I have moved it to a brighter spot and will be more diligent about fertilizing, and hopefully will have some amazing pics to share when it blooms!
And yes, lesson learned - repot immediately upon arrival. Thanks everyone for your input!
