Whats wrong with this

Seeing burnt tips, leaves are dark green. Nitrogen toxicity. Flush your plants out. How much/what are you feeding them? They are in flowering, need to back off the N and start giving it more P and K

I had a couple of my plants do that this run. I thought it was because i watered a day late once and had some leaves droop pretty bad.

That look like a minor nute burn (top leaves point burn). The spots on those leaves means you either dropped some nutrients/water with nutes on the leaf and you did not clean it up. Nutes on leaves + strong light = produces that. If you are sure its not that, then it's ph fluctuations, dont worry about it, if it appears on more leaves then you need to start checking things out.

Too much N, maybe P deficient based on the purple petioles

Looks like you got nutrient solution or something on the leaf where it burned in the middle

yup I agree I call it splash damage from feeding getting sum on the leaves and then under the light will do it everytime and you for sure need to back off the nitro I don't normally agree with flush cuz sumthing is wrong but in your case id give a good flush

I have to disagree on the flush here, flush will wash most nutes (micro and macro) from the ground and it can cause severe problems afterwards if not replenished right. I would say just go with simple stable ph-ed water next watering.... I only recommend flushing when its a serious damage (a lot of leaves affected and you can't seem to find the problem of it).....

We still don't know if soil or hydro....
I can say, "complete water change", and it make perfect sense to do. Need more info..

Looks like light damage from when the leaf was wet. Either the leaves were laying on top of each other and transpiration, left the surface wet, and then leaf moved and burnt by magnification of light or foliar feeding/bug treatment with lights on.

very minor burnt tips, back off just a tad.
