I have a (thai) chili in my kitchen. It seems to be fine overall. One week ago I discovered some white spots on the bottom of the leaves (see image).
Whatever it is it does not seem to be moving. It is also kind of hard to scrub off. I tried it with the fingers, that does not work very well.
Some leaves are more afflicted while others do not have this symptom. After a search I found this question. In this question the plant seems to have scale. While the white spots do remind of what my plant has, mine does not have any brown or dying spots on the leaves. It also seems that her/his plant has this on the top of the leaves too.
So I wonder is there any reason to be concerned? Can anybody confirm scale or anything else?
After some more research I discovered a condition named Chlorosis (Edema) which is caused by overwatering. I have to admit the photos I saw look a lot like what my plant has.
The strange thing is that I did not have the impression that I am overwatering. I always wait until the soil is really, really dry. Might this also be caused by putting too much water at once?
