I'm just turned 17, and I'm a bit worried that if I get a CIEM, mh ears will continue to grow, and therefore I will no longer be able to use it. Does anyone know at what age your ears stop growing so that I could get my first custom in-ear monitor?

Your ears are constantly growing/changing through life. I would say you should wait till around 20 or so, that is when the rest of your body will likely have slowed/stopped growing so much. I got mine as a 21st birthday present to myself and I love them but indeed my ears have changed a lot from my original impressions due to a lot of weight loss soon after. They still fit nice and snug but if I got new CIEMs the impressions would look drastically different on the inner ear section. These are some of the thing you need to be aware of when you decide at a young age to get monitors. 
 
I recommend custom sleeves for your IEM's now so that you save some money and still get a lot of the advantages you were looking for.
 
Other options include CIEM's with soft canals or what my CIEMs have which is hyper-coating on the tips that get more snug when they are inserted.
