My plant is an indoor Fukein which had been doing really well and growing new leaves. However recently some of its leaves have started to shrivel and white spots have started appearing on the leaves before they fall off. Please see pics for details and kindly let me know what I must do. It's still growing new leaves but after a while they start to shrivel.

Looks like powder mildew to me. Check this out.

Seems like it is about dead.
I would be interested in seeing more of this plant. This is the first time I have heard of an indoor fukien tree. I always thought all plants were evolved to be outdoors.
