Phal with one yellow leaf and yellow on leaf tips, help!

[fezz2619]

I received a two-stem phalaenopsis for Christmas a few weeks ago from my boyfriend who told me the florist said to water once every 6-8 weeks. I have since researched and found that that was incorrect! I was away for one week and when I returned, one of the bottom leaves had turned completely yellow. Also, the tips of two of the green leaves have a little bit of yellow/black on them and two blooms on one of the stems shriveled before they bloomed. There are still three other blooms that haven't opened, the other stem appears to be fine.

I moved over the weekend, so here are the before and after conditions:

Before: the orchid had some light indirect light, but not a lot and wasn't watered for two weeks.

After: the orchid has indirect light all day and I watered the roots using a spray bottle. These conditions probably haven't had an affect yet because I moved the orchid last night.

Here are the pictures of the yellow leaf, pot (which is a glass jar), roots, and the leaf tips. Please help! This is my first and I absolutely love it.
