Needing fertilizer or too much light?

Hey everyone, zone 7b here. I have a dozen varieties that I started on 1/25 in Ferry Morse seed starter. Up potted Saturday 3/7 into these 4inch pots and added another light/shelf. They were bottom watered on Thursday 3/5 last week. They were potted up into coast of Maine organic potting mix with about on third moistened coco coir added. That’s all the water they’ve had since then. Several leaves looking “taco”-d and yellowing.

Do they need less light? Or maybe fertilizer? They seem well hydrated.

Let me know your thoughts and thanks in advance!
