what are these marks on my leaf?

I woke up this morning and checked on my plant to find one leaf had weird marks on them, i'm pretty sure it happened over night.
Does anybody know what its from? I was wondering if I could just pinch it off but I was uncertain as its part of a bud site and I don't want to do anything that might stress it or something

Whatever the issue is I will be thankful if you give me some ideas on what to do with it

did you spill any nutes on it?

If it's just on the one leaf, you might have spilled some nutes or something else on it. If it doesn't spread, you can just leave it -- no need to pinch it off. Most of the leaf is quite healthy, so just leave it be.
