I would wait another week before adding nutes ... and then don't start them at a full dosage but only about half. And no, weird leaves at the beginning are pretty much par for the course and mean nothing. Those early leaves can take strange shapes and colors but these traits usually don't continue when the 5-fingered fan leaves show up...
Good luck! I'm growing a Pink Kush as well although mine is and auto and I'm in DWC...
