I planted a few cuttings. 6 of them. They started the grow beautifully. Then the leaves closest to the pot started turn orange pink brown and dry up an die. I asked four growers what's going on. They all say too much water or not enough water. That doesn't help. They definitely aren't under watered. I gave it some fertilizer two weeks ago. ( does this plant even need fertilizer). The leaves are still dying off. Please help so I don't lose all the leaves. The stems are healthy. It's just the leaves. But no new leaves are growing at the base of the plant.
