Signs that Im done growing taller.?

I just turned 17, Im 180 pounds(muscle), and only 5'9, maybe 5'10 because thats what everybodys been telling me. I never, hit a growth spurt, even though I am very athletic,healthy, have good genes for height. My dad is 6'0, while my mom is 5'2. I exercise with light weights,never pushing myself or over doing it, play high school football, and basketball for fun. I take protein shakes, drink a lot of milk, and take a daily multi vitamin every day. Im very healthy when it comes to eating. I still have a baby face with no hair anywhere except my private area and arm pits. My brother whos a year younger then me just finished his growth spurt and is now passed me by an inch and looks more older, facial and body wise. I have never hit a growth spurt by the way. So what are the signs that im done growing?
