Defoliation done right ?

Well lollypopped. You've left 3 nodes above and taken everything below, and it looks like you left plenty of leaves for photosynthesis. The plant looks happy and I hope you have a great finish.

I used to pluck but imo it's not good

No.

That is way too much for me. I generally do not defoliate. I will remove leaves that are within about 4" (10cm) of the soil to make watering easier. Then I will use low stress training to pull the branches apart so the leaves get better airflow and light. Then, I only remove the leaves that are shading bud sites, Remember, the leaves are solar panels that collect the energy to grow flowers. Cut off the leaves and you harvest may suffer.

Looks good to me. I always take out the shade leaves that point toward the middle of the plant because they cover a lot of potential bud nodes. I also remove any leaves that cover any bud nodes, no matter where they are on the plant. Oh, and start a diary! You'll get a lot more help if people can look through your grow and know the history of it. Good luck and keep up the good work.

A bit too much to my taste
