Is this nute burn?

I have these 2 plants that I'm wondering if they have nute burn or if it's light burn or something else it just started so might be impossible to tell idk
Watered ab a day ago with nutes so I'm thinking it's nute burn
There are some shiny tip leaves
Not really worried about it unless it progresses I'm just wondering what it is

Maybe, if so you've caught it early.
Remember that "the damage is done" & any burnt tips aren't going to get better.
Watch the rest of the plant for any indication.

Have fun
