Maybe I should try Colloidal Silver . you know the stuff used to wash fruits and veggies.
A wilt might manifest itself with such symptoms in seedlings, I just don't know. If so and nothing is visible it is likely to be fusarium or some sort of root fungus.
you're plants look pretty wet, that can't be helping any fungus problem. and that cube with the big greenspot looks kind of ominous... i've used garden sulphur before but i'm not sure thats a very 'broad spectrum' fungicide.

Physiological or Nonparasitic Leaf Roll:
Physiological leaf roll occurs during wet weather or when transplants are first placed outside. Typically, the leaves roll upward, at first appearing cupped but eventually rolling continues until the leaflets overlap. Overall growth of the tomato is usually not affected. Fruit are not injured by this condition.
Otherwise, look hard for thrips.

yea looks like you got some algae (sp?) and possibly over watering
They look wet because I sprayed them before taking pics.
The algae is almost inevitable with rockwool but harmless.

That is spot on!
Last week I got one of those 6" plastic dome that fits over the seed tray.
So the temperature in the last week changed from a cool 18-20C to about 24-26C and humidity from 30% to 72%. These plants are in shock!
They should get back to normal after a week or two

Habman, the exact thing happened to me. I had 5 trays that were not covered and 3 that were. The three that were covered got a case of "mold" or "fungus". I think the high humidity + heat is what did it since the 5 uncovered trays did not experience the "sickness".
I sprinkled yellow corn meal on the surface and it either slowed it down or killed it. I will know more when I start transplanting to 9 oz cups tomorrow. If the fungus/mold is in the soil I will give it a good coating of corn meal again. This worked for me on my baby nagas. They got a case of the "green" that was visible around the cup/soil interface. When I transplanted them to 6" containers, I mixed cornmeal in the soil and coated the outside of the root/soil mass. The baby nagas are coming on strong now.
Ms. Pam made me a believer.

fungus and mold just love humidity, if you can avoid those domes altogether after they grow their first true leaves thats best.

Yep, that's what I always used and it works wonders!
