Hello my friend😉
Do not worry it's normal some plants of the same strains have different genetics the main thing is that it is in good health
You should simply continue so your work is neat your culture is clean👍
Continuous your LST is trying to pinch your secondary apexes that will allow you to have a more homogeneous canopy thus a better luminous penetration and consequently a better yield
Good luck for your grow🌱
May the force be with you💪
