Weird that it is only on the roma’s. All the buckets are grouped together in the same space and filled with the same potting mix.

So far no problem with the others. Are roma’s more sensitive to sun?

We just harvested some Cherry tomatoes -- which were from a volunteer plant which I'd yanked in mid-January, when our tomatoes are usually flatlining (SoCal desert - planted around Labor Day the year before).

Surprisingly, those held up really well, considering that we've been in triple-digit temps for over a month now here in Warmthville...no sunscald at all.

I don't "do" anything tomato - but wifey loves 'em - but the report is that the little cherries were quite good, but an attempt at making juice was a bigtime fail.

My three Roma plants were/are in my greenhouse, which is now with the plastic removed, a shade cloth house.

Anyway, when they first started getting ripe, the first two or three roma tomatoes were flat on the end, and that brownish/taupe color. I didn't see how it could be calcium deficiency as I use Tomato-Tone on them..Anyway, I thought at first it was blossom end rot, but it wasn't..it was just like the tomato was stunted on the end, and had tha brown skin..

It was just the first three tomatoes, and after that, the rest were normal. I guess it could've been sun scald as it was getting super hot in there before I started running a fan 24/7, and then finally removed the plastic covering.

I am not sure whether or not the Romas are more suseptable to sun scald than other tomatoes.
Sun scald on fruits and stems frequently occurs when you do one or two procedures together :
1)if you prune suckers (unproductive vegetative growth) off tomato plants; this makes for easier fruit picking, but at the expense of the plant shadeing itself
Also , when you prune the suckers , it forces more of the plants energy into fruit production and earlier ripeness.
2)if you water plants in bright sunlight; the droplets remain on the stem or leaves, and act as magnifiers of sunlight causeing sun scald.
Sun scald generally occurs when there is high humidity, very bright sunlight, and a slow evaporation of water droplets.
Some people water vegetable gardens very early in the morning, but best policy is to water at night to increase water transmisson to encourage deeper roots,
and to minmize water evaporation .
