not it is not supposed to look like that! How have you been taking care of it? how often with nutes water and such. did it get light during a dark period? either way, NO!
i dont think it got light during a dark period but it not out of the question since someone else has acces to the closet ;( but regardless it still stinks tho is good or bad?
looks like a genetic thing and looks pretty healthy. I have seen plants like that before, just can't remember the name for that type of leaf formation.
