The cotelydons (the first leaves to emerge from the seed post-germination) aren't meant to live long once the plant becomes established. What I see looks like a plant that's possibly being overfed. Easy to do with a seedling.
No tiny flying bugs around the soil?
Merit 75 will get rid of your fungus gnats forever. You can buy it off ebay for really cheap.How soon after transplant did you notice the necrotic margins? Good that there are no bugs, fungus gnats have been driving me batty and have killed off even more pea seedlings.
In any event, if the new soil has any fertilizers in it already (e.g. if the bag said no feeding necessary for however many months), then that's how the overfeeding would be occurring. Keep using water only for it, and know that when bottom leaves go yellow and die it usually means the plant is also growing very well and it's translocating nitrogen from the lower leaves to the new growth. When new growth is explosive it is also often a light green in color (anticipating the next query).
Really though, it's pretty much growing as it should.

I wouldn't use CO2 with anything that's going into the root zone.
What? THAT's how you're doing it?
You do know that CO2 is carbon dioxide, and not oxygen, right? And that plants need oxygen (aka O2) in the root zone, right?
You can keep doing things this way, but don't be surprised if you have more problems along the way.
I have a twelve twelve from seed plant that's on day twenty tree flower and still has its cotodendryns. Can't believe it actually she's pretty large to still have em.The cotelydons (the first leaves to emerge from the seed post-germination) aren't meant to live long once the plant becomes established.
