Can drinking a cup of beer with 2/3 of its 356 cm^3 volume filled with water once/week stunt your height growth? Started drinking at 7 or 8 years old

Bad idea. Bad idea to be drinking alcoholic beverages starting at 7-8. I am not sure however that this may be solely the reason for one's stunted growth if that is the case. So many other factors such as genetics, malnutrition, etc.
