Sour Tangie mini hunt

The seeds were germinated about a week apart. They are the 3 center solo cups, the bottoms is the oldest and the top the youngest. The 1st one was a runt and slow grower, but is going strong now. The 2nd is the same size as the 1st, just with a bigger 1st set of leaves and a much smaller 2nd set. The 3rd is starting a promising ascent. I ran out of my soil mix, so at the last minute I amended some of my old soil, where the roots haven't fully decomposed, with some Dr. Earth 4-6-3, kelp meal, and some Coast of Maine Lobster Compost. It never had a chance to cook, everything in that tent is using that mix and you can see the deficiencies.
