Spray with 1 part full cream milk to 9 parts water if increased airflow does not clear it.

Hi Owdboggy ! Is that a standard procedure as I have the same issue in my greenhouse (Crassula ovata), and on my citrus trees ?

Certainly is the organic solution put forward by a lot of folks. Appears to work too. There are Fungicides on sale which may work, but never tried them. Do be careful about spraying anything on Crassula (or any member of the Crassulaceae), they tend to take a great dislike to anything sprayed on them and turn black and die.

cant see from the picture really but, it probably is powdery mildew, make sure it has enough air flow as this is a major cause of it along with damp and heat.
