Kdog20started grow question 4 years ago RH 45-55%, 21-26c- is this potential powdery mildew/ wind damage?
Plant is closest to fan and only one affected. Was pot bound in its early life and has been suffering from some deficiencies due to this-twisted leaves, some yellowing/ brown leaf.
If PM I will destroy the plant
