red spots = orchid measles!

Hi,

I am having this problem with my complex - Paph global challenger x (tingtagel x sparsholt).

I've had it a for 2 or so years, there are actually 2 plants in the pot.

The problem on its leaves has been there for maybe 2 years slowly killing off the lower leaves. To begin with I tried cutting them off, but they are discolouring quicker than they are growing.

The damage is only on the top of the lower leaves, and starts on the leaf opposite not the leaf directly above.

I repotted recently, big healthy happy furry roots.

I grow on a heat mats in a north east facing window

Help!
