Phalenopsis full bloom but dehydrated leaves

[meldog]

Hello Everyone! (freshman post)
I bought my second phalenopsis about one year ago, having overwatered & killed my first one. Envirnoment: This one lives in our small bathroom—it fogs up with every shower, has a somewhat eastern exposure in Madrid (sunny, dry), and typically gets good morning sun. Usually it shows decent condensation in the pot after a shower.

Last year it went thru a cycle, sent up a new spike, and even new leaves! Started re-budding in January and as of now has approximately 16 blooms over 3 spikes.

I just noticed the top leaves shriveling and not so green, so yesterday I soaked the whole pot—avoiding leaves, crown-- in water for 10 minutes. Within 12 hours the top leaves had perked up. The majority of roots greened up considerably.

Today, the roots are less green, the top of the medium (bark) seems dry, but there is very good condensation in the pot. One of the blossoms has shriveled and come off.

Questions:
Shriveled leaves says that the roots aren’t bringing enough water,but must I repot with 16 blooms on? How do you know when air roots are rotten, since they’re always gray anyway? If the initial part of a root is bright green but the rest is gray, do you snip just the gray part and put a little cinnamon on the wound? Since I soaked the pot yesterday, can I do so again since roots look less green?

I have all that I need to repot, I just hate to do it before all the blossoms fall off on their own.

Thanks so much for any wise words!
