bottom leaf problem or not

My plant is finishing the first week of flowering now and it is going well.. i have noticed tho that the very bottom leaf is turning a yellowish collor and it is now curling a lil bit wat is this plz help

This could be normal or it could be a problem. Could be an N deficiency as you aren't using as much N or it could be that they aren't getting as much light down at the bottom due to the bigger leaves blocking it.

Do you have any pictures? I'm interested because I am also trying to figure out if I have an N problem or if it is something else.

cant put pics up no camera but maybe later today im gonna try borrowing my friends.
