Leaves curling down? Please help

Two of my plants leaves have started curling down, was wondering if anyone can identify what’s up with them. I have done some research and think it could be nitrogen toxicity?

strain is Alaskan purple, growing them in soil they are two weeks into flower. Using plant magic old timer bloom nutes but have still been giving them a bit grow as well but only 1.5 ml to 5l was going to stop using this start of 3rd week. Don’t know if this is what’s caused it??

Any help greatly appreciated.
