Gigi & Ken....they sure are fun to watch grow.
They seem healthy & hope they stay that way. Kind of an interesting side note, to me, I potted up one of that batch of seedlings a couple of weeks ago as an experiment to see if it could take the outdoor temps. Planted it in a solo cup with a mixture of Hoffman's seed starter soil and perlite. That one is really deep dark green but not quite as large as the others. They were all sprouted in jiffy pellets. Can only think that the soil is the reason for the difference in leaf color. Am also noticing that other seedlings started in that soil have that really dark green color.
