Because half the leaf looks great and the other wrinkled—- I’m going with heat and wind burn. Not nutrients, but environment and or genetics. Show the whole plant— one pic looks perfect and then just a wonky leaf. I think you are good!
I’m not familiar with the brand of nutrients you are using but I’m not seeing much nitrogen going in. That being said, the actual yellowing occurring on your leaves looks a bit similar to an iron deficiency. 🌱
