    Default Unsure- mesophyll cell collapse or black spot on a plant with a keiki- please help!

    Hi there, my first time posting on here and it's about my first orchid I was given two year ago.

    It has developed dry black lesions in the middle of two leaves, is slightly wrinkled and yellowing and has a few black spots on leaves developing. It also has a new keiki that has sprouted and I'm desperate to find out what's wrong with it and save it!

    Does anyone know what's wrong with it and what I can do?

    Ps ignore the semi circle marks on the leaves, an old candle injury from when I first got it. Poor plant.

    The sunken spots in the middle of the leaf looks like mesophyll cell collapse, this is likely to be due to cold damage. The black spots are probably blackspot, a bacterial disease. You can stop if from spreading by sprinkling cinnamon on it. The spots are here to stay though.

    Careful with the candles next time. When ur reading websites just know that those are guidelines not recommendations. BTW anyone know why we use candlelight to measure orchid light?

    All I know is that the measurement is supposed to be the amount of light that a candle makes at 1 foot distance. I guess it was a fairly standard amount of light.
