I'm thinking more water than twice a week. In my greenhouse, Aerangis
luteo-alba var rhodosticta (or whatever it is being called now) gets water
every day on its cork slab. It is thriving. Your roots look to be similar.

I am worried abou my Aerangis Verdicosa. The leaves seem to shrivel then
turn this pinkish
orangy color & drop off. I have lost two other African species the same
way.
What to do?
They get watered twice a week in this warm weather & reside in my slightly
warmer intermediate g/h environment.
Any tips would be appreciated.
Cheers Wendy
