@texasbamma - Your Fiddle-leafed Fig is fine. The black spots are minor blemishes or imperfections and are best ignored. You can expect the occasional loss of some lower leaves as they age and healthy new ones are added on top. Older leaf dieback typically starts with some brown patches. Again, nothing to worry about.
Although your plant does not show any obvious signs of too little light or water, in general, the more direct indoor light this plant receives the better. Unless you added a couple of inches of soil to the top of the original rootball (assuming it was repotted), then you are letting it get too dry between waterings. In general, it should be watered as soon as the top of the original rootball feels almost dry.
