I have 3 plants here that have these burn looking Mark's on them. They are autos about exactly 3 weeks old. I'm using 2 dimmable 1000 watters all my other plants seem fine tho and dont have these marks on them any help is appreciated. The lights are set to 750 and are all the way up to the ceiling. I have 8 foot ceilings.

Ok. Thank u bro.
Yes that's what happened. The solution was around 300 ppm if I'm not mistaken, was a few days ago. Should I just do plane water u think next watering and check runoff?
Looks more like nutrient burn but still hard to tell. The one pic with the leaf anomaly seems like a drop of nutes was spilled on it early on, or something similar to that
I'm starting to think its nute burn cause on the tips it's kinda crispy
Hard to tell. Try taking a couple more photos a little more steady and clear
