Pleiospilos bolusii getting spots

[pencilman]

Hi,

We have a 7 year old Pleiospilos bolusii that suddenly started getting spots this last week. We have had it for about 5 months now.

It was watered about 4 days ago and now have these dark patches all over and is oozing some clear liquid on the one leaf.

I attach a picture of the plant where the spots are visible but not the liquid.

Any idea as to what is wrong with the plant?

Thanks

jacques
