Looks like mite damage to me. I have similar markings on mine before I finally got rid of the buggers!

I just saw the same marks on mine as well, but like you said I can't find any bugs. Are mites that small? What would you reccomend?

If it's mites or thrips, they are tough to eradicate. Most "do-all" sprays that claim mite control don't quite "cut the mustard" so-to-speak. Kelthane is the prime chemical registered in US for mite control. Not sure what options exist for non-US growers. Higher moisture will help to keep them from getting established. Mites usually get going in very dry environments and take over on Juniper, certain orchids, etc. Prevention is easier than cure - hate to say it.

that looks like mite damage. Very hard to get rid of. Try Neem Oil.

Good information, any known "home remedy".

I agree. it looks a lot like mites

Yeah I would say mites too.

thank you all!
I did a treatment with neem oil.... will see !

I have eliminated spider mites with Neem Oil, Don't be afraid to give it a second application in a week or so.
