Is this light burn?

Is this heat or light stress? The temperature are low 80s' humidity in the 40s. I'm using spider farmer sf4000 at just under 80%. It's a gsc..I grew it last year with a 400 mh/hps and had no problems. This is my first run with an led.

Plants would be happier if humidity was closer to 64% at those temps. The leaves are under a lot of pressure with that high VPD; leaf temps is too high. Which is why we see the serrated edges turned up on leaf edges, she's trying to cool down

Read about VPD when you have a chance, it will help you.
