Wilting Flowers, not quite completely dry roots
I have a phalaenopsis that's about a month old (well I bought it about a month ago) and some of the flowers are starting to wilt (interestingly the flower that bloomed the most recent is almost 100% wilted). I wonder if it could be a lack of water because while some of the roots are a healthy green but there's also some that are almost white (see picture - sorry about the quality). Also the phal is still in the original pot that I bought it in and looking at it more closely, it looks like the medium and the roots are packed too tightly so maybe re-potting needs to happen (also see picture). I have the phal on my window sill at work and it gets some sun in the afternoon. I used to keep the window open but then I realized that 90+ temps are probably not good for it.
So I think I'm going to repot it this weekend and see what happens. Any other ideas/insight into why the flowers are wilting? Oh, just had a brainwave - should I feed it some orchid food? Thanks for the look and help!
