Am I being too panicky? Help/advice pls!

[bnaz]

Hello. c: I've had my two orchids (both Phals: one mini, one 3") for about a week now. They were both in bloom when I bought them, and I repotted/fertilized both upon arrival. I've got them both in their own personal humidity trays, sitting in a thin layer of water in a 5-gal acquarium to help raise humidity levels, since I read this is what orchids like. Today, I noticed a couple of the blooms on my mini Phal are looking a little softer, like they're wilting. :c I hope I'm not doing something wrong. The leaves on the larger Phal seem to be a little softer too. I might just be panicking because I'm a new orchid owner, but I was wondering what your advice might be?

I have a hygrometer. Outside of the tank, it reads about 70-degrees and 48-50% humidity. Inside the tank, it averages about 60-63% humidity during the day and 73-degrees. Looking at my hygrometer now, it's reading 71% humidity. It seems to increase nightly, then dip down during the day. Is this alright? Should I water and fertilize my plants tomorrow? I don't know where to begin with the troubleshooting-- or if the wilting flowers are even really a problem.

Here's my current set-up (it's still a work in progress):
