Help pls, Painful leaves below

That looks like too much nitrogen... your leaves are very dark green... take it easy with the nutrients. It's easier to fix a deficiency than to deal with over-fertilization. I would not use any nutrients for the next 3-5 waterings, then it should get better... Good luck moving forward 👊🤞🏽🍀

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.

She needs a bit of nutrients, she's just switching into flowering, I would give her a light feeding schedule :)
