GCS Gorilla Glue and Critical Purple

That’s is a way too much nutrients for an autoflower. Especially at the beginning of week 3. Nutes should be like 1/4 strength and work your way up. I am currently growing the CP and speaking from my experience. The curly leaves is most likely due to way too many nutrients. I started with about .5 ml/l of grow only and has worked great for me. You should ramp it back before you have big problems! Auto’s don’t like nutes like photoperiods, a little temperamental in that department. Good luck with them!
