Weed and feed leaf curl recovery?

[attml]

I have over 40 varieties planted this year some of which I had to plant in my Dad's yard due to available sunny locations in my own yard. Last week I noticed my Black Krim and Mortgage Lifter, which I have planted on one corner of my Dad's house, started an odd looking leaf curl. I kind of dismissed it for a couple of days because we had cooler weather, but after no change I decided to do a search on "leaf curl". It turns out that the leaf curl I have looks like it was caused by a specific herbicide in common weed and feed fertilizers. I talked to my Dad yesterday and asked him if he had used any weed and feed? He replied "yeah, I put some down last week and I put more down today". Ugh! He didn't know any better and I can't complain too much since it's his yard, but I am bummed because I was really looking forward to trying those two varieties this year. Also, I have Brandywine, Cherokee Purple and Stupice all in the same vicinity (which haven't shown any damage yet). My question is what should I do? The lower half of the plants are all fine. It is only the new growth that have the leaf curl. Should I leave the plants and water heavy? Would you even trust tomatoes that you knew had chemicals in them? Should I try to move the plants to a different location? Or should I just forget those plants and bury my much smaller backup plants in a different area? The damaged ones have been in the ground for a month and had tomatoes already on them? This whole thing really stinks! Any help would be appreciated!

BTW, Happy Mothers Day to all the Moms out there!
