Miltoniopsis leaves limp and folding

[The Orchid Kid]

I teased them out of the pots yesterday for a peep at the roots and most of the roots are a light brown colour and a few slightly squishy. Is this the first stage of rot? What colour should they be and how firm should they feel. The medium at the bottom of the pot was quite damp.

I am not totally sure I am looking at under watering....maybe the opposite?

many thanks for all the advice so far everyone!
