First set of serrated leaves twisted and curling ?

Hey guys! I’m a new grower 18 days into the journey and have noticed that on 2 of my 7 seedlings the first set of serrated leaves have twisted and curled under the Cotyledons but are still a good green color and doing fine. One out of the 2 like this had 3 cotyledons on it. My secondary question is will the slower seedlings catch up to my 4 faster ones, or do I eventually call it for them ??

So here’a the info on my grow so you have a better idea: Strawberry Glue Bag Seeds. Cheap 600w led, brand is (DIPNGX Grow Light) I will be upgrading and also getting reflective Mylar for the walls!!
I’m in Michigan growing indoors, I water until I see small runoff then monitor the soil daily and water when the cups are light and dry to the first knuckle. I PH between 6.0-6.4
The environment in my closet is always in the mid to upper 70’s with my humidity always between 50-70 depending on when I refill the humidifier. Also since it’s winter here and cold I have a warm humidifier to help keep temps up!
I’m using Happy Frog while in the solo cups.
18days in so their still young. I don’t see any discoloration or wilting on any other plants.

Here’s the pictures of the twisted slower ones

And here’s the other ones that have grown faster!

There's always genetic variations from seed, though the one looks bad. Just keep an eye on the next leaf sets to emerge and see if they don't look better. Right now, no time to worry.
Also, next time try and take pics with the purple light off

Alrite I’ll keep a closer eye to see how the next ones form. And I’ll definitely take pictures with natural light next time. Actually I think I’ll take better pics of them when they wake up later today and replace these pics on this thread.
Thanks a bunch and good lookin out!
