Some of the leaves on my spider plant are kinda droopy?

i dont think they're called leaves but you know what i mean! they branch out a little n then bend n droop over only the outer ones. the others look healthy but the outer ones not so great, and kind of yellow. the pot its in doesnt have drain holes on the bottom but there is a line around the pot where the water drains from if there is too much water. but i dont water it often. maybe once a week or when it feels dry. any suggestions?
