Little help please, wavy leafs

[Bizal]

Hi
I'm new here and a first time grower.
A few of my seedlings have this wavy leaf.
I thought it might have bin to much light so removed on light. (Luxx clone led)
They where starting to turn a lighter green. But since removing the light, they have turned back to this

Info
3 week old

do you have drain holes? usually best to put the drain holes on the edges of the circle so even if its laying on something flat it can still drain

Mmm, ok
That's a good idea. I'll do that tomorrow.
In your opinion, does that look like a water issue?
Its by a glass door and the temp in the box can get down to 60° sometimes.
I was thinking maybe it was that.
I also had 2 lights in there, but I took one out.
I thought it could have bin to much light.
I think what ever It was, I got it under control. They seem to be doing better.
I hooked up a humidifier switch and a mister with a fan

Looking back on what I said It’s all preference just make sure there’s drain holes is all I meant, but your plants honestly look perfect not a single thing to say
