Hi, can anyone help me with this mini monstera? I don’t know if I overwatered it, I waited a while for it to dry out a tad before watering again and this plant has always done really well. The base of the plant has started to yellow. No pests noted. Leaves are starting to become soggy and develop black spots on one side of the plant. This same side of the plant’s stems are wrinkly looking but hard and not squishy at all. This plant has grown super quickly but suddenly is experiencing a problem. What should I do?
