Gin and Orchid Man,
Thanks a lot for ur replies. Yes, I did wipe the underside of the leaves and they were stained with some light orange kinda thing. I bought a bottle of spider mite killer from my local orchid farm and I have sprayed the medication according to what the staff told me. I guess things are going to be ok, and will keep my fingers cross from here.

Thanks for ur help again.

regards
