Thanks for the info, too late on watering them though, I did it this morning before work after seeing the first reply. How do you tell when the top 2/3 is dry? THe containers are a little small to stick a finger down in there, I'm afraid I'll disturb roots or something. The top layer did feel dry, some of them soaked it up faster than others but it probably wasn't dry that far down. I think some of the peat on the sides is from when I first planted them, I filled the trays and then once I watered, it mostly sank down but some was still around the edges. I have been blowing a fan on them each evening for a couple hours but when I saw them curled up like that I turned it off thinking it was too strong even on low. I've also been turning on the heat when it drops down to 50 to bring it up to 55-60. Should I stop doing that? I will use your suggestion for the rack. I didn't think the lights would make a difference. They aren't hot to the touch and I put the thermometer in the basement right next to a tray under the lights and it didn't seem any different than 6 ft away. I know the Bibb in the pellets doesn't quite have any true leaves yet, they are just starting to come up, but, should I thin those out now? They seem a little crowded to me. What about if 2 seedlings came up right next to each other? Do you snip one off or wait until they are bigger? My peppers just germinated 4 days ago but in 2 of the cells, seeds sprouted right next to another one. Thanks for all the help.

Check for mites, remove those curling leaves and spray.

It could be stress, too much sun, insufficient roots for the amount of sun, overwatering, lack of acclimatization, etc. Some viruses have that as a symptom. The variety might be used to a more temperate climate. I would remove the oldest leaves of the plant if I were you (although that is experimental advice to stimulate new leaf growth, which leaves might not be as prone to curling). Maybe give it some extra potassium/phosphorus, too, to help the roots (without adding extra nitrogen, unless it's already low nitrogen). If your tomato is determinate, you may want to be more careful about removing leaves.

Thanks for asking. It doesn't seem any better, but it doesn't seem any worse, either. I gave it a good soak and looked for signs of insects or mold. But I haven't called the county extension office. Treebarb, its two types of apple trees that are twisted around each other. gjcore, thanks for the book recommendation. I've lived in homes with mature fruit trees before, but I've never grown them from saplings before.
