Any
ideas on the extremely dark colored leaves if it wasn't light? Lack of
some kind of mineral in my starting soil? I would think that
could affect fruit seedlings the same way.

Hi,
I have grown tomato seedlings for years, and having the light too close
is never an issue. When the leaves touch the fluorescent bulbs I raise
the bulbs just enough so they do not touch (1/4"). The lights also run
16 hours a day. A small fan keeps the air moving, which moves the
seedlings, which inspires strong stocky stems.
Having the lights too far away gets you spindly stems, as the seedlings
reach for the weak fluorescent light..
Transplanting tomatoes into too cool outdoor soil can set them back as
you indicated.
Later, Tom

If it's not a disease I would tend to think too
much light or the light source too close. I had some tomato
seedlings I started one year and kept the light too close the them.
The leaves got darker and darker on them almost to the point of looking
black until I planted them. They never died, but they took about 2
months to recover and start growing normally.

Hi, I'll jump in with my two cents' worth, and suggest that maybe
the air is too humid (although I realize that inside in the winter,
that seems unlikely). It the plant isn't transpiring, it isn't
able to bring nutrients up from its roots and will die of
malnutrition. Maybe next time you can start them when the season
warms and grow them in a sheltered spot outside? Muffy Barrett
