Would need to see a picture to know but it is far, far more likely to be just environmental effects, or as Jean says, cultural effects (which is a better label ;), than any virus.

"Soot" at the edges could mean many things including nitrogen burn. Leaves "curling" is often just tomato leaf roll - a defined and discussed condition that is nothing more than the plants response to stress of some kind - usually excess or inconsistent watering. Google 'tomato leaf roll' for more details and photos for comparison.

Purple veins are common when soil temps are cooler and there is excess watering. And any bloom that is not adequately pollinated will die and fall off - normal.

Spring weather and over-feeding could easily be the cause of all your problems but without seeing the plant it is just guessing on our part.

This is in a container so that also opens up a whole other set of possibilities.

Thanks Dave, very helpful info. I am trying to post some pics but finding it difficult.

put them on flikr or photobucket etc and then post the link to the album.

Here are some pics of the plants. They are heirloom yellow pear and mr. stripey.

Here is a link that might be useful: Flickr

As I said in your other thread, I don't see the "soot" you refer to. Appears to be off-color leaves. Instead of virus, much more likely to be cultural/environmental, even the leaf curl

I can see some slight discoloration on a few of the leaves but I honestly don't thing it is of any concern unless it rapidly increases. Overall your plants look just fine. Take comfort from the fact that if is was one of the common tomato diseases they would look much worse or even be dead by now and this time of the year problems are 90% of the time just stress and environmental

So I'll stick with the points made above - this is "mostly just spring weather effects on plants growing in containers" diagnosis for now. TN weather has been as bad as mine here the past couple of weeks and my plants make yours look like perfection. ;) As the plants adjust to their growing conditions it should disappear assuming no excess feeding or watering. Did you read the info about 'tomato leaf roll'?

Can't tell the size of the pots from your photos but they appear awfully small by comparison to the plant itself so I hope they are big enough.

Cool, thank you for the advice. I'll just continue the mission and hope they live. Thanks.
