I would not defoliate at this point 'cos you can easily see through the plant and from my understanding its good to defoliate only when there is lots of leaves and ------you +really feel like the plant is not needing it. I've seen too many diaries with too much defo and you can clearly see how it affected the yields in the end. Even I did too much at some point in my first grow..
It's all up to you to decide but I feel like it would be better to leave them be for now 👌
Hey :-) I would only defoliate at the bottom, I never take leaves from above because they are the basis for the buds to the light :-) If at all I would bind the leaves down or up but not cut them off
