I tried a different approach/goal of topping and lst for each plant.
Plant 1: I tried to train it away from the corner with lst and i cut off the branches growing directly into the corner. 2 toppings
Plant 2: The goal was to get as many mainbuds as possible and this was the most i dared to top and lst. I liked this one the most but the additional stress cost me a couple of days delay compared to the other 2. 3 toppings
Plant 3: This plant is a sort of baseline for the others. I decided that after i accidentally broke off one of the two new stems after topping while doing lst. I topped the remaining stem once more and did careful lst on the biggest sidebranches to even the canopy out again. 2 but effectively 1 topping
