<span class="link_user">@Al_Green</span>, I think thats super mild nutrient burn. Light burn typically causes the tips to curl up and the leaves overall to start taking a taco'ish shape (edges curling). But if you're worried about light burn you could also try raising the light a few inches. Good luck!
<span class="link_user">@DudeGrowsWeed</span> thanks for the response. I just put up a close up pic.
I also thought it could be nute burn but when I looked back through pics I could see that even before I added nutes there was a lighter shade of green on 1 or 2 leaves. It is only on new growth leaves on the highest points. I will ease off the nutes a little and see what happens.
