Yellow leaves with grey/dark outline

Hey bro! 👋 Everything's good with you! You've got some grown girls, and that little deficiency at their age is a normal thing! I’d even say your harvest will be healthy for consumption! 👆 Maybe you did some defoliation on those branches earlier, or perhaps the yellowing leaves are just poorly lit. It's all normal - the plant is trying to move what it can towards its flowers (water, nutrients). Big developed leaves will yellow, dry out, and fall off. This is all normal for the end of flowering! 👌 Keep your room clean, collect the fallen leaves, try not to help the plant shed a leaf, don’t cut it; when the plant has taken everything it needs from it, it will let it go on its own. Your only task is to pick up that leaf and remove it from the cultivation area! 👆 Good luck, my friend! ✊😇
