Hello and Thanks for Reading. I have a Masdevallia Kimballiana that stopped blooming about 3 months after I got it. Besides that, it was very healthy until now. It has begun dropping adult leaves. The leaves are not brown or mushy nor yellow. I water once every week with 3 parts water and 1 part 10-20-10 liquid formula. The temp in my house is 74 F during the day and 65 F at night. They just drop off from the base and don't grow back. Please help!
