I had a similar problem and it was diagnosed as sunburn/sunscald. My problem was due to hardening them off too quickly (too soon of a move full to sun).

Other people had similar problems with plants that got a lot of rain and then had a lot of bright sun. The leaves grew very quickly and couldn't handle the intense sun.

Someone else had a similar problem but it was due to birds and their special way of recycling.

The advice was to not worry about it. New, all green, leaves would soon form and the plant would be fine.

It worked for me!

Seems to have gone away with that rainstorm we had yesterday. You're right, might be sunscold from improper hardening off.

Looks just like what happened to my peppers and maters last year. I too rushed transitioning them from indoors to out. My plants were much smaller than yours, and I had entire leaves turn white and fall off. I assumed it was sunscald, and soon enough they all sprouted nice green leaves. Gave me a good scare though.

Not sure what zone, I'm in Boston.... I got 3 tomato plants from the nursury (6" pots) and because of the intense rain was not able to plant them. As a consequence they sat on my back porch in the rain. I always heard wet was ok for tomatoes? I did make sure to make sure they weren't carried away by a flood :-). Anyhow, now 2 of them have speckled white leaves. Any ideas? Is it bugs, disease, or what? Should I start from scratch before I plant in the ground???? I almost killed an aloe, so I need all the help I can get. Thanks.

Boston is Zone 6. I would simply plant them and not worry. They should do fine.
