Hey Avazquez , i would not defoliate it because of stress, as well, remember, when you close the grow room it become much more bright and light. That's because the reflective surfaces are working together. So if you see a shadow it doesnt always mean that there is a shadow when you close the door. Anyway leafs are there to help the plant. I would only remove the bottom leafs if you're very nervous about humidity and mold but not so otherwise. Hope this helps ! 🚀
