Hello!
Not sure if this is the right place on the forum, hope so! My kalanchoe is very sick, has been for a while, and I can\'t seem to match it with any diseases I find online. Does anyone know what it is or how to help it?
The leaves get a grey mold on them, then they turn yellow, dry out, and fall off. It clearly starts at the bottom, on the lowest leaves, and works its way up one by one. I\'ve treated the entire plant twice with a spray but it doesn\'t seem to help! I really hope someone has an idea!

Regards,
Donna
