Hello fellow bonsai enthusiasts!
I recently got my first Japanese white pine, after some research i noticed that one indicator for spider mites is that the needles turn greyish. I checked my needles and actually all needles have a greyish color on one side.
It looks like this:
Do i need to worry about spider mites? If not, how does this “grey” color is different from the grey color that come from spider mites?
Thanks in advance
