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?
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.
