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.

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.

Yellow blemishes1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.
2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher?
Other suggestions maybe?

Yellow Leaf Tips with Brown Spots – What Could This Be?One of my plants has yellowing tips on some of its leaves, and there are also brown spots forming on these yellow areas.
Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?

Leaf Troubles: Nutrient Overload or Calcium/Magnesium Deficiency?What’s happening with these leaves? The tips are curling up, and the DLI is below 45. I’m unsure if I’m overfeeding nutrients or if there’s a calcium and magnesium deficiency. What do you think the issue is?
Please help me, I need to feed in a few hours.
