Welcome to HCM
We understand your concerns
Height is a genetic factor. Your father and mother together determines it. Growth retardation is different story. It happens due to mutation
of certain jeans. You don't have that problem. Consider your mother's height also.
Secondly, exerises oesnot guarantee you growth, they guarntee health and vitality. Don't confuse. Exercises such as pull ups can increase height by just millimeters. Don't fall prey to quacks.Smoking
cannot hamper height growth. Wait for your turn of sprut. But such height growth happens upto 20 years. You are just 17. Be healthy and eat leafy vegetables and sleep straight facing up.
Good wishes for your future
