There are different techniques:
(LST) Low-stress training. check: https://dutch-passion.blog/lst-cannabis-low-stress-training-for-better-yields/
(HST) High stress training. including supercropping, and topping.
The most important thing is to first see how healthy your plants are before you apply something. Healthy plants can take a beating. First start with light low stress and if that works after the 4th or 5th branch a HST like topping.
Sativas grow longer nodes. Low stress or scrog is a nice way to do this. Too much stress at once can cause hermaphodites.
So step by step. Happy growing! Im curious for your proces en yield an taste experience..👊
