White specked pattern on outdoor plants
Almost every plant in my garden (Southern UK) is covered with a spreading white pattern. No evidence of insect actitity such as spider mites, whitefly, aphids, etc.
Definitely not powdery mildew and affects only the upper area of the leaf.
I thought at first that the pattern was part of the plant, however it has spread onto most other plants now.
Will attempt to upload some photos, any help appreciated!
