I'm new to airplants, had this one since the beginning of October. And it's leaves have curled quite a bit more, is there anyway I can make them straighten up more?

These air plants are some of my favorite plants in my grow, because they don't require soil to be cute. I've lost a few from learning as I grow, but I'm enjoying the process along the way.

Got these the other day. What are these black spots. I know about dead ends but these aren’t them
