A growth spurt happens during puberty. By age 18, puberty is over and you grow at a slow pace.
What you need to do
If you want to growth taller, you need to get a balanced nutrition, exercise regularly and avoid unhealthy habit.
Why
When puberty starts, the pituitary gland releases HGH(human growth hormone), which is responsible for the growth of bones. At the end of puberty, hormonal changes cause the growth to stop or slow down.
