Masdevallia rolfeana brown spots??
 

Hello,

I recently purchased this orchid online and have noticed a brown spot on a leaf. The leaf has also turned a slight yellow color as well. I have only owned the plant for 2 weeks. Any thoughts on what this could be?

What temperature are you keeping it at and how is your air circulation?

Temp is around 68 F while airflow is minimal.

Welcome to the OB!
Your temperature looks good but these guys really need good air flow. The brown spot was probably caused by a drop of water that didn't dry quick enough and you will probably lose the leaf.
