Help pls, Painful leaves below

Das sieht nach zu viel Stickstoff aus… deine Blätter sind sehr dunkel grün… lass es langsam angehen mit dem Dünger. Es ist leichter einen Mangel zu beheben, als eine überdüngung. Ich würde die nächsten 3-5 mal gießen keinen Dünger verwenden, dann sollte es besser werden… Viel Erfolg im weiteren Verlauf 👊🤞🏽🍀

This looks to be from a lower node on the plant, maybe it got banged around. I would not worry about it. if anything pinch that off and let it focus on the main buds up top on the plant. The leaves are extra dark green and lush so its getting excess N from somewhere despite you not fertilizing. The leaf in the far right of the pic does have some markings on it that are reminiscent of thrips so I think the other user suggesting it maybe thrips might not be wrong. Keep an eye on that, I don't know them to cause issues with younger leaves like that in the center of the pic. but they do like to fuck up mature leaves.

Looks like thrips. Nothing to be panic about ✌️

She doesn't appear to be mature enough to be going into flower although I have seen people on here that will do that. Deficiency in some Micro nutrients will cause yellow malformed leaves as well as lack of Potassium and Phosphorus. We learn with each grow so don't forget to take notes. If she's an Auto it appears her conditions aren't up to par to grow vigorously. if it is a Photo I would have waited to switch the light schedule until I got her healthy enough to handle flower stage. Flower stage is where they become more temperamental and susceptible to issue in my experience.

too rich on N so it could be either PH swing or a little lockout don't see the need to feed it i suggest to keep watering for a week or 2 then u can ask a question again what to do pls do more pics of a plant (side, bottom, top, whole)

Sie Brauch bisschen Nährstoffe, sie wechselt gerade in die Blüte, ich würde ihr ein leichtes düngeschema verpassen :)
