Hi Sandy, my experience is with Irish Setters, not Gordon, but alot applies to all the Setter breeds. At 7 months your girl will be very much at the leggy gangly stage, and has probably had something of a growth spurt recently. Correct weight is more a case of look and feel than actual numbers. Look down on your puppy from above, does she have a 'waist', and can you feel, but not see her ribs. If so she's probably fine. If not then just be more careful with food amounts and treats, puppies shouldn't be 'dieted' as such, but she's at a life stage where her shape is changing.
