Hello thank you
@Bilber, I appreciate it.
Yes, I'm talking about the stretch of pure sativa and the space between the knots it causes. That's why I use indicas in 12/12. Even if some grow more than others.
It's a solution, clone and throw the mother plant. Personally, I wait for the repotting to bury them deeply and it goes well afterwards.... normally

.
Afterwards, it's also my fault, I didn't pay attention to the height of the light and the intensity. I have only myself to blame. I didn't think they would come out of the ground so quickly. A few hours after planting, they came out.
They are vigorous, but that's not a problem either, I have secured the plants the others should not get as tall.
But I take note of your advice for clones and throw the mother plant, I'll test

. My grow closet measures 60x60x140cm, not much space.
