repotted bonsai problem

repotted bonsai problem

I repotted my schleferra bonsai after 9 years in the same pot and it is not doing well. The leaves are turning black and are dropping off. I used a bonsai potting mix that I bought at a flower show and fed it a bit of bonsai fertilizer. Plant is definitely not over-watered and it is getting a fair amount of bright light. Is there anything else I can do? I've had it for so long; I wish I hadn't repotted it :(
