i was changing my water and the fan cuts and sliced a little chunk ,off one of the fingers from the upper leaves,does this take energy from the plant are cause the leaf to die
It will take some energy. Will it die. that can go both ways. but no worse then topping or something. Hell, stoney snapped his main stem and it healed and is still growing.
I'll send you a pick with some of the abuse the plants in my "sickward" have undergone later today. You'd be surprised how much they want to grow sometimes.
