I think your cinnamon spray copied from rays would be s good start as a precaution. This could be over crowded light problem. Before you purchase next time look over the leaves and choose healthy looking plants.
Are the bulbs smooth or wrinkled. If they are wrinkled its not been getting enough water. Good Luck, Keep us posted.
Thanks guys for all the help! i will most definitely look into black sooty mold! and yes the pseudobulbs were shriveled , but it's weird it not like a normal shrivel its more like ridges only going up and down on it.
