Hello everyone!

I just discover lots of very tiny ( pin point size ) brown grain
underneath
some leaves. I have looked at them with magnifying glasses but they don`t
seem to move. I was wondering if they were actually bug or just dust? Some
of my phals are deteriorating and I don`t know why!

Can you help me?

Hi Claude, could it be red spider mite?
