Is there something wrong with my friend's Tolumnia?

This summer was chaotic and I did a poor job watering. I noticed limp leaves and some spotting, which did not spread. When I became more regimented in watering they perked up and are now blooming. While they need to dry out quickly, the larger bark might keep them too dry. I don't mount mine because mounts are a huge hassel for me. Fertilizer has never seemed to matter much here. They get something at every watering, fertilizer alternated with cal-mag, Ray's magic probiotic, and a once a month clear flush. Also, when mine are getting sufficient light, they are blushed red. Hope this helps.

Thank you so much! My own Tolumnias are in 6-8mm chunks of pumice. Those seem to be doing well for now (we bought otr Tolumnias in similar health conditions during the same week).

As for the blushed red colour, I'm not sure how to give the Tolumnias more light. They get filtered morning sunlight (2500-3000 lux based on the Lux Light Meter android app) every morning from 6:30 to around 11, after which the conditions are bright.
