Can any one tell me what's wrong with my sage

[bethixboop]

As subject suggests can anyone tell me what's wrong with my sage? Or what I've done wrong and how to fix it.

I'm not sure if it's because I have got the leaves wet?

All comments and help greatly received

I think you are probably right. Sage have slightly hairy leaves to trap moisture in their native Mediterranean climate. Where are they being kept? How much sun do they get? My only other thiught was something like wooly aphid, as I have to enlarge your pictures quite a bit to get a close up so it's not very clear.
Pick off the worse ones and improve ventilation.

It looks like powdery mildrew to me, you can get a foliar fungicide to treat it. It tends to develop from fluctuation in temperatures and overhead watering. If you can avoid watering the plant and find it a sunny spot it should recover.

Same here - improve the airflow, and it likes it dry ish and warm but it'll pretty much cope with anything except humidity.

If it's in a greenhouse, place it outside for a month or so. The parsley and other herb (marjoram?) will be better for it as well at this time of year.
