white spots on herb leaves?

[Headfry]

Buzzingtalk - I have the exact same thing.....even taken bits to Wisley, they seemed to think Red Sprider Mite!!! ????
Really annoying as the plants are otherwise great but as its the leaves I wish to use....well I dont like to when they look like they do.

Ohhh, did they say anything about how to get rid of the mites, and if the plants would get better? On my online research journeys I found other people in the US with the same diagnosis...so maybe that is it...

Apparently they don't like damp wet conditions so hopefully there is a spider mite genocide going on in the garden as we speak, seeing as the affected plants are overed in snow

white spots on thyme

Hi everyone, I also have this problem on my thyme which I planted this may and now these little white spots have appeared on the leaves. I must say that I did have rosemary and sage in the same patch last year and they did have the same spots. I wonder what causes this?! anyone can help?
