Strange leaf deformations

Firstly sorry if this is post in the wrong spot. I have just started my first grow indoors ( done a couple of outdoor grows from random seeds but nothing I really invested into) I have 6 Kosher Tangie seedlings that are 6 days from sprouting. The healthiest looking and largest of the bunch has some funky ass leafs. It's just the rounded on the bottom. They have this wavy look. I was wondering if anyone has seen this before. Not really alarmed by it just though it was weird...

picture isn't really good , but how's your temperatures ? at plant level ?

also i see that your plants have some drops of water on them , that is not recomendable if you have them on fluor bulbs there is no big deal , but under HPS thats forbidden . it will burn your leaves spay them on lights off
If its just a few leaves and your growth is going ok , dont worry about it , as long as new growth is coming fine and it seems it does. .

Those plants look 1000 percent normal and healthy idk about the whole no spraying under an hps I've never had leaves get burned from that. But an hps is not ideal for veg your baby will stretch. T5s are great they are efficient and put off low heat which means you can get your plants closer to the lights which really helps node spacing which in turn creates more bud cites which obviously results in more buds in your yield

Thanks for the input. Yeah they're under t5 so a no need to worry about burnage. I wasn't really worried and the there's good new leaf growth everyday so far. I thought it was. Unique as none of the 5 kosher tangies have those wavy leafs. Maybe she's a keeper

Those first wavy leaves are called cotyledons and they protect the seed in its shell, they will yellow and die off soon as normally happens
