By the third picture I would say that's a Sulfur deficiency or pH fluctuation, or mostly the plant started asking more P-K and Ca. My humble opinion.

Re:
Here's more pictures, and the top 3 inches of soil is dry to the touch before I water again usually. I must've messed up the past couple days or something. I did just add that Mars hydro ts600 though. Light stress?

Newer growth is lighter in color and thicker than the other leaves. She was under my humidifier so maybe drinking too much? Dry organic amendments so no additives in water. Several other grows in same feed schedule and no issues

What happened to this seedling?
This seedling out of 5 is the only one not looking good. Everything was the same for all of them, but this one took a turn for the worst. It's ok if it doesn't make it but I do want to know what you all think might have happened to prevent it in the future (or save it now)
