Im pretty sure its not from the light. If you use CaMg you may have a toxicity and need to put less or none of that.

No diary + limited info = impossible to give best answers. Not light or heat stress, but surely someyhing to do with pH and/or nutrition. Slightly over fed. Developing calcium deficiency. Too wet and too much humidity. Incorrect pH...........could be one or more of those things, if not all of them. P.S. - always post pics taken under normal light, pics taken under grow lights are hopeless for seeing details.

My opinion is when you are growing indoors with fertilizers and soil you hardly run into any deficiencies, but toxicities all the time. I guess you are using GE/TA or Advanced Nutrients fertilizers and you overfed her.

Is the damage mostly facing that low light or is it more evenly distributed? It would be more efficient to try to LST/HST your tall plant down to canopy level and run your lights the same distance.

https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg Potassium likely. No one can tell if its nutrients or temps because you have no diary with that information posted. Best to start one on your next grow and fill in the fields.
