Wilty weird leaves

Like the title says….
-Soil (OF,promix, perlite mix)
-3-4 weeks old
-all the same strain, from same pack of regular seeds
-haven’t fed them anything or added anything weird
-LED lights in a tent ,usual conditions 75-80 degrees f, 50 -65% rh
??? keep waiting for them to outgrow this but they’ve been kind of weird the whole time since sprouting
Any ideas?

Is the medium completely saturated or just a small portion of soil? Do you have good air flow? Fresh air? They do look a little sad and underpowered...

I recently up potted so it’s currently just moist around the transplant zone probably.
I’m pretty sure these were old seeds. They took a long time to sprout. I’m just not familiar with how older seeds behave. Maybe it’s got nothing to do with it though

saturate the soil, especially after a transplant, you probably have dry patches causing issues

They look okay not great. When exactly did you repot? I repot one time from 32 cup to 5 gallon. repot can cause stress a few days. otherwise water too much or not enough. I satureate soil leave each water. don't barely water. more info needed but I think can easily grow out fine.

Since you recently transplanted the roots aren't getting much air, did they look better prior to transplant? Particularly the third one.

What's of?
Fox farms ocean forest or whatever? I'm gona go out on a limb and say that's the culprit. I say it often, I hate that shit. The plants to me look like they have too much nutrients. This will happen to me if I toss a seedling into a mix with Gaia in it.
Weird twisty curling leaves, droopy, spots of necrosis, etc etc. I find when there's high p-k in the soil these weird leaves happen.
I know you said you didn't feed anything but what was your mix %'s for the medium? Really, at the very most I'd only add a very small amount of amended soil into a seed start, and really that's not true at all I wouldn't add any. But let's say for whatever reason I HAD to. Well I'd add a small layer on the bottom of the pot and fill the rest with something inert like promix, or sunshine #4
Just because it's an old seed doesn't mean it will have mutations. That doesn't occur. If the genetic line has mutations, and they're dominant genes they'll show through in the offspring. Those don't look like genetic mutation. It looks like a ECe problem.
That's my 2cents

They were like this before the transplant, they were in small starter pots(my term?), roughly the size of a solo cup and a half probably. The medium in that pot was jiffy starter mix which is pretty much void of food i think, after once they were about 2 weeks i top dressed that with a little bit of the OF(ocean forest never had problems before really)pro mix 50/50 mix. I transplanted into these 1- 1.75 gallon containers cause I thought maybe the roots needed it. And that was just a few days ago so maybe they’ll perk up idk. Seems different than a usual ph, npk, watering issue for some reason just hunch i guess. idk.

It's tough to say. They're pale so they look hungry but the leaf thing is odd.
I just don't use foxfarms seems like everyone is always having issues with it.

I’ve had a similar problem in the past. Drooping plants and limp looking leaves, the plants certainly weren’t overwatered or thirsty.
It turned out to be low humidity even though the hygrometer said it was 65%.
Perhaps turn your humidifier up a bit or add another and check back an hour or so later to see if they’ve perked up.

I could be way off, good luck either way mate.
