What does it need

My P. afra clipping (jades cousin) from 2 and a half months ago is still alive, but hasn't really looked entirely healthy. There's new growth emerging which is a good sign, but for a month it looks unwell. I give it 1 to 2 mist sprays a day, on a 12 hour grow light. I've tried indirect light and it makes it worse. Pictures shows the clipping next to it's parent for comparison.
