started some tomatoes - 3 varieties, 6 of each in peat containers...used
organic potting mix (from home depot) watering with rain water....they are
couple of weeks old. I place them outside whenever it is sunny day...if
there is no sun, I use florescent lights 12 hours or so.... several have
first true leaves.........none are dark green.....they look sort of light
green color....I see the tomato plants in the stores look beautiful lush
dark green.........what am I doing wrong?
Does the 'organic potting mix' include any fertilizer? It should say so
explicitly on the bag. Unless the potting mix comes with fertilizer
you will need to add some to your seedlings. Perhaps fish emulsion
(if you stick to purely organic). Dilute to half-strength.
You didn't describe your seedlings as being tall or leggy, so I don't
think they lack for light. It is possible to sunburn your seedlings if
you move them from flourescent lights to full sunlight too quickly.
They need to be acclimatized.

Turn every day to avoid plant leaning in one direction. Monitor
if too much light; if so, move a few inches away. If too many
sunless days, resort to grow lights. Put out to harden
as soon as frost danger past -- but be conservative; don't
rush it; if your area can get sudden frosts. Good luck!
Can Chlorosis exist in seedlings?
Could be bad seeds?
Grow lights may be better than shop lights for plants. Try transplanting
some of the plants to better soil and see what happens. For cold season
areas a heated propagation frame is nice to have for seedlings.
