Why are the leaves on my azalea looking grey with dark spots underneath?

The leaves on my azalea look dull and grey with dark spots underneath. I've watered the plants well but the leaves haven't improved. Someone told me it's probably red spider. Would this be right?

It's more likely to be azalea lace bug, a sucking insect that works underneath azalea leaves and causes the classic discolouration and spotting you have noticed. These insects are triangular in shape and have lacy-patterned wings. They are active during warm weather. Spray with Yates Baythroid, Lawn Grub and Insecticide. It sontrols a wide range of insect pests of lawns, ornamentals, vegetables and outdoor areas.
