I wouldn't worry about it.
I think, if anything, that living the weight trainer lifestyle promotes natural growth because of the high-calorie balanced diet we eat. My little brother, 17 years old, grew 2-3 inches this year and gained 10 pounds living off of pure crap (diet 90% carbs, tons of ice cream, etc) I sometimes wonder how much bigger he'd be if he ate well.
