I got a Ginseng Ficus 3 months ago and up to the last couple of weeks its leaves have been turning yellow. Meanwhile the ones which have been healthy have developed white spots as if lining the outer edge of the leaf. It's spring going into summer and I don't know if it's a climate change problem (it's kept indoors). I have no idea, as it's my first time having a Ficus. I've been watering every so often when the soil gets dry. The weird thing is that it seems to be healthy enough; I have new leaves budding but they die shortly. Help?
