Tip of leaves starting to curl

Hey hows everyone doing? This is my first plant and my first post. I recently bought a grand daddy purple plant that was ready to flower. i transplanted this yesterday am and noticing the tip of a few leaves is starting to curl down. not on many just a few. I am not sure what this could be realted to. If anyone knows if this is normal after transplanting or if this could be something mor major like my lights or if it needs food? Thanks for any and all help.
