Oncidium/odontoglossum with black spots on leaves HELP
I have an oncidium/odontoglossum that has a pretty large amount of black spots all over the leaves. The oldest black spots have turned into what lookes like a brown/tan-oval-shaped-lesion. There are a few of them really taking over the ends of the leaves. What could this be? I am a very newbie... I have 3 other Phals. and they seem to be doing very good. What can I do to stop the spread and get the plant into better health? I cant figure out how to post pics. When I get that figured out I will get them on. Thank you for any suggestions.
These are pics of what my plant was looking like. I have since done surgery and cut off the tips of the plant that are very sore looking. I cut them with a new and sterilized exacto blade. I also sprinkled some cinnamon on the new cuts. I have also sprinkled some all over the plant. I am trying to up the humidity level and air movement. I am also in the process of adding some extra lighting to my plant area. I hope this works. Thank you for your time.
