Hello 👋
Why clean the leaves now, why cut them? If you still have free space in boxing.
Use this space to stretch your bush width and give light over the entire area of the plant.
Leaves need to be cut when you have no empty space at all.
And I see that you can just tie up, make a LST, stretch, the top and all the cola are tilted - and the whole bush will receive light evenly.
Look at the example of my diary now a variety - Kees Old School Haze - is just in this state, stretched.
Cutting the leaves you lose a lot of useful things! So many!
Try to never cut the leaves until you learn how to do it literally professionally.
To be a rope, brew tea and after 20-30 minutes of pleasant work in your garden you will have 100%+ good result if you save the existing leaves and just pump the bush.
If you cut something, lose in the quantity and quality of the final crop.
You should succeed, it's not difficult.
Be careful and do not rot too much so as not to break the branches.
Good growth and crop🙌
