Hi all!

I moved my Meyer lemon plant indoors for the winter in September, however today (Jan 27) I have noticed the leaves starting to turn yellow with these translucent spots. A few affected leaves have already dropped. Anyone know what this is? Fungus? Disease?

Thanks!

I'm pretty sure it's just a reaction to the lower light intensity indoors as opposed to outside. In the second picture you can see where the leaf was bent and the base is good while the tip portion is yellowing.

I agree with CalPolygardener, low light. You know you can clean the leaves if you
think you have insects with a mixture of 50/50 water and rubbing alcohol.

Yep, low light. It is dropping the leaves that don't get enough light to justify supporting them.
