First Set of True Leaves Wrinkling and Folding Up

This is my first time growing and as such do not have a lot of the equipment yet so I apologize in advance for the lack of information.
I planted my germinated seeds about 10 days ago and they all sprouted and were looking healthy until I noticed that the first true leaves coming in looked weird and wrinkled like this on a few of the plants.

This picture was taken at around 7 days. By this point around half the plants had true leaves like this and even the ones that didn't seem to be growing a bit slower than the guides I have been reading. I left the plants to grow and this is what they look like now at day 10.

(I know I'm not supposed to put two seedlings in one cup but this is my first time growing and I wanted to experiment) The one on the bottom did not look too wrinkly when the leaves were coming in and they turned out like this but the top one looked quite similar to the first image and it turned out looking like that.

This plant is by far my healthiest looking one (I think). It never had any wrinkled true leaves and this plant is easily the largest out of all of them by a pretty large amount. The brown on the cotyledon is just leftover from the seed casing.

This plant is the same plant that was in the first picture but 3 days later. The leaves are still wrinkled but are growing.

This plant also has the wrinkling on the true leaves. I'm pretty sure there are more things wrong with this plant than just whatever is making the leaves wrinkly as it was further from the light than the rest.

This plant looks fine and it is actually the shortest and looks like a darker shade of green than the other healthy one but I do not know why its leaves are so narrow and small compared to the other one.

I am growing in "Natural and Organic Professional Container Mix" from Better Homes and Gardens
I watered for the first time 5 days after germination with Pittsburgh tap water that I let sit for a few days to get rid of the chlorine.
Ever since then I have been watering it a few spoonfuls of water whenever the dirt seems dry.

Poor choice of medium. It’s loaded with nutrients. Go buy a bag of Black Gold Seedling Mix. Absolutely nutrient free. Buy some colored plastic cups at the same time. Or up pot them to a SLIGHTLY larger container.

Happens as seedlings adjust ( acclimate ) to your medium. They usually pull through.

They're a little overwhelmed.
They'll come around.

Its been about a week and all of the plants have continued growing and all of them except one are growing straight leaves now and the leaves that were wrinkled are appearing to go back to normal. However, one of the plants keeps growing new wrinkled leaves and is growing pretty weirdly.

This plant has been in all of the same conditions as my other plants and been watered just as often. The rest of the plants look pretty normal. If you look closely it actually looks like the first set of true leaves has 3 leaves and the second set is going to have 5. Was wondering what is up with this plant. It also looks like the top of the plant grew into a leaf so I'm hoping that it isn't a mutation and it keeps growing taller.

Just looks like a mutant seedling
Some grow out of it..some are destined to be fucked..sometimes they turn out amazing..sometimes they dont .
