It sure sounds like fire blight. Perhaps you planted your seeds in
contaminated soil, else it may be some kind of mineral deficiency if
you planted in sterile potting soil.

I used a peat/perlite mix.

Also are they warm enough?

About 70F, which may not be warm enough. Humidity 25%-30%.

Does your water have excess minerals (dog urinates on seedlings? ;-)?

I use rainwater that I collected last fall.

Tiny insects such as spider mites?

Nope, I checked that out right away.

I really appreciate your thoughts, just nothing seems to stand out. I thought it may be fireblight, but I would find that odd as there isn't any fireblight in the orchard where I did the crosses.

Thanks again,
