@Mwiltz. I have been packing and shipping plants and haven't had time to check in on the NGA.
The browning/dropping is probably due to the stresses involved in bringing home a new plant and having that plant adapt to new growing conditions.
You can spray all the leaves, top and bottom, with insecticidal soap. Or just continue to wipe off both sides of each leaf with a soft, damp cloth, and do so daily. It may take a week of so to rid the plant of these pests.
I would always opt for a south exposure. Keep in mind that these are trees in nature, so you are making the plant adapt to low-light. The more light the better. In my opinion, a north exposure is the worst exposure possible for these plants. Light air movement is good, but having that movement generated by AC/heat vents is bad. That air will be very dry, not good for a tropical plant.
If you have well-draining soil, and plenty of drainage holes in the pot, it will be very hard to over-water these plants. My plants are now outside and they get watered pretty much every day. Your plant won't need that sort of watering, so just water when the top of the soil looks real dry. You'll reduce the watering in the fall/winter.
Keep in mind that because these leaves are huge, every little flaw is accentuated with them. Just find that bright spot, water every 3-4 days (or when the top of the soil is dry), hold off fertilizer for 2-6 wks. (when the new leaves are looking good), and keep an eye out for insects/mites. Your Fiddle Leaf Ficus should be fine. They are tough plants.
Good luck with your plant.
