question

ar the 2 smooth leaves supposed to fall off?

Yes - eventually..

well i was jus askin cuzmyplant is 2 and a half weeks and its lookin like there gonna fall off

As long as the rest of the leaves are looking healthy that's quite normal. Eventually even some of the big fan leaves near the bottom of the plant will die. When the plant realizes they aren't getting much light anymore (because the rest of the plant is blocking it) the energy stored in the lower leaves will be consumed to produce new growth at the top.
