Masdevallia with yellowing leaves

Sorry for the quality. I have already had one rapidly yellowing and then falling off, leave on my Masd. Ayabacana.

It is grown in a temp range from 12-20 degrees celsius. No noticable drought. It is potted in spagh, is weakly fertilized with a commercial orchid fertilizer ever 2 or even 3 weeks. What am I doing wrong?
It takes about 5-7 days for the spagh to be dry.

Thanks!

my masdies are all in fine bark, but every now and then they just dump off a bunch of leaves. doesn't seem to bother them too much.

but i'm no masdie expert; wait for one of them to weigh in.
