Can I defoliate lightly during flower after week 3?

Hi friend, You got the right instincts. Some times an "hair cut" can be such a relief ;) I like to remove some of the big on top to unblock some light to the lower canopy. After that if there's any in the lower canopy in shadow areas that I can't unblock I remove them too. Good luck ;)

hey there Nubzzz, turns out defoliation is not really what you're after. That's because first off when you close the tent the brightness is really much bigger than when you're opening it and poking inside. as you can see , your plant is sort of growing in a bush shape , normally a plant grows towards the light, here you see all parts of the plant growing symmetrically , meaning when the tent is closed there's light that's coming from all directions. Meaning the shadows you think you see are only the shadows that are there when the tent is open and your head is in the way. when the tent is closed the shadows arent there . Anyways next thing is this : during flower you want the plant to flower. if you remove leafs the plant will make more leafs, it's just a distraction at the end. This is my advice based on some understanding how light and shadows work. Hope this helps growmie ! 🚀

Yeah you can. Just be selective. Don't remove a leaf just for the sake of it. Make sure removing it will benefit other parts of the plant.

yup lite defoliation to help with light penetration to expose some lower bud site is fine. Happy growing
