Looks like burned

So I think a have a problem. The problem is that my plant looks like a bit burned . Its leafs are burned a bit. I made a mistake and accidentaly spilled somw nutrient over a leaf , and so it got burned / disappeared . The problem is that I saw more leafes look burned , but I didn't spilled on the nutrient ( accidentally ) . The advantage is that the more it grows yhe less it looks burned . I think that it recuperates . I am growing outdoors and I need to say that these days there is a lot of sun. This may be the answear . But I wanted to make sure I won't be dealing with a problem.
