yan402answered grow question 18d ago Hey growmie, both pictures show completely normal stem development.
This happens a lot after topping, or LST, the plant is just reinforcing the structure and building up support tissue. The little bumps are lenticels (natural breathing pores) and the darker line is normal pigmentation from stress hardening.
Nothing to worry about, this is how strong stems are built. Keep her happy and she’ll carry weight like a champ later.
Good luck growmie 🤞🍀♥️
