Is this nutrient burn or some sort of deficiency?
These are the tops of the plant lower leaves are all good

There are indications of light stress, so I'm thinking the light is too intense. The leaves were getting more energy than they could handle. Increasing the Ca and Mg could help because there are indications of deficiencies of them, but the leaves otherwise look well nourished. Changing the light might be enough.

Just spitballing here and you would hopefully know what you fed her to know if I'm even in the ballpark, but it looks to me like it got heavy on the nitrogen and it's starting to cancel out some of your potassium as you can see in those leaf edges.

id say you're lights too close and also getting pretty hot on them plants that close. the burn looks like light burn, and how the pointy parts curl inward that usually indicates heat issue's

if it lets you zoom in. this was a first i did along time ago. but 35C and a close 600w light. only trying to point out the curly tips here. if you want to see bad light burn go into my pics ive made a nice post about it and had it answered by nick along time ago

Looks like nutrient burn. Same thing happened to my last plant (also my first plant so I was clueless) and the leaves started out like this but continued to just get more burnt. Just continue to regularly water

It looks light the lights are too intense or too close either way ….the dry Matt looking leaf reminds me of a week ago at my place when I had similar issue …fixed by moving light up and dimming slightly ….also possible minor calmag issue but move the lights and wait a couple of days …if they look fine when you check them after the 4/6 hrs of dark for sure it’s the lights ! If not try foliar spray wth cal/mag

I concur
