Yellow Leaves

Some of the leaves on my seedlings are yellow instead of green. Didn't know if this was due to lighting or fertilizer or temperature.

The seedlings that I really notice it on are Columbine and Delphiniums.

These are indoors under lights or outdoors? In pots? In what kind of soil?

Could be a nutrient issue, but my first guess would be over-watering. Tell us more about how you are watering.

They have been indoors under fluorescent tubes. I took them out into my garage this weekend (still indoors and the garage is warm now). They are in peat pellets and I typically water from under when the pellet starts to get light in color.
