    Sounds like your plant has a fungal infection (due to a damp environment, mushrooms). Could you leave the greenhouse door to allow the moisture to escape or turn on an exhaust/venting fan?

    Sounds like to much moisture

    Pick off the leaves with the black spots, it’s a fungal thing. Don’t put them in the compost pile, they go to the garbage can.

    We have mushrooms in our raised beds when things get too wet. Sounds like that's the culprit. Can you open the door and bring a fan in (if you don't have one for ventilation)?
