Thanks for the tips, everyone! Okay — I’m gonna go with the watering less, and only in the morning thing. Should I also pluck off the affected leaves and/or spray with a dishwashing liquid mixture?

I’ve had this every year on my flowers and tomato plants as well, and its a fungus that doesn’t really harm the plant too much. You can use Seven powder, it helps.

I go to an environmental school, and I got this post conveniently while I was on campus. Brought it to a prof, and he says Powdery Mildew.

Hope that helps!

It looks like some form of mold or mildew. Try watering less. Tomatoes seem to best with a good soak 2-3 times per week – not every day watering. Water early in the day (as the mold/mildew can come from wet leaves at night.) If you can (if I remember correctly it’s potted, right?), get it somewhere where it gets as much direct sunlight as possible.

Looks more like a form of powdery mildew to me.

Hard to tell from the photo but it looks like White Fly to me. Usually a little soapy water & plucking off the infested leaves (check the underside for eggs) will help.
