Spots on tomato leaves

Asked May 28, 2013, 5:26 PM EDT

I have 5 tomato plants and at least 3 have what looks like dry or brown spots on some leaves. The plants look healthy except for this. Any ideas as to what this is?

This looks like sun scald on tomato. The plants should have been hardened off before planting outdoors. That is putting the plants out for one to two hours a day for one day. Then two to three hours a second day. Three to four hours the third day until you have the plants out for a full eight hours in a day. Then put them out for a day and over night. Then plant them. These look like they went from greenhouse or indoor growing directly outdoors. They will likely recover from this.
