Hello, friend! 👋
Your girl is already grown up, and having a deficiency at the lower levels is normal! There's no need to fix anything or try to overfeed her with nutrients! 👆
You don't need to remove the leaves; yellow leaves are also necessary for the plant!
Where there's little light, the leaves turn yellow, dry up, and fall off. This is normal for a plant at its mature age! Don't remove the leaves; the plant relies on their presence! When the plant no longer needs them, the girl will drop the leaves herself. Your only task is to pick up the fallen ones from the surface of the substrate and throw them away! 👌
Good luck, bro! ✊😇
