Put your light up asap! You are cremating your plant bro. Light to close to the plant causes this

I can’t put the light any higher. And no the leaf doesn’t come out.. I was leaning to more of a light/heat stressed but wasn’t sure. It’s a es300 light should I cut back on the power since I can not raise it!?

When looking at my plants compared to others mine are a deep green. Is that normal? Does it mean anything bad or good. Just strange how two different genes are so dark compared to others on this site.

whats wrong with the leaves?
Im sure this is nothing to worry about but i just want to know what it is. Is it genetics or is it a deficiency that i can sort out. Im only feeding water at the moment. Also is there a name to refer to this condition? Because its not twisted or wilting?

Calcium deficiency? I'm a newbie, but this is my first major issue and I'm thinking it's some sort of nutrient issue.
