I'd say you are caring for it too much. Just let it be. Figs are quite resilient and it will probably come back still.

I have two plants. One was turning dark brown on the edges. That would undoubtedly be from over-watering. The water meter read dry all around and moist in the middle. Water meters don't measure moisture, they measure electrical conductivity. Fill a clean cup part full of distilled water, insert a clean water meter probe and note it reads 'DRY'. Sprinkle some salt in the water (makes the water conduct electricity) and watch the meter move to 'WET'. It's much better to use a 'tell'. See below. I soaked it and the nursery said to take take it out if the pot and ket the rootball dry out. After I did that, I repotted and soak it. The advice to remove the root/soil mass was to pull the excess water out of it. Putting it back in the pot and soaking it undid what would have otherwise been beneficial. I also cut the brown off of the edges. No problem in doing that. You should find this piece about Good Growing Habits helpful. The shortest route to green thumb status starts with learning all you can, instead of trying dozens of different things and ending up totally confused by the mixed results. When you learn what to do beforehand, you don't spend your valuable time getting bit on the butt by mistakes; rather you use your practical experience to validate what you already learned. Practice that, and you'll leave the 'trial-and-error crowd' standing in your slipstream. Using a 'tell' Over-watering saps vitality and is one of the most common plant assassins, so learning to avoid it is worth the small effort. Plants make and store their own energy source – photosynthate - (sugar/glucose). Functioning roots need energy to drive their metabolic processes, and in order to get it, they use oxygen to burn (oxidize) their food. From this, we can see that terrestrial plants need plenty of air (oxygen) in the soil to drive root function. Many off-the-shelf soils hold too much water and not enough air to support the kind of root health most growers would like to see; and, a healthy root system is a prerequisite to a healthy plant. Watering in small sips leads to avoid over-watering leads to a residual build-up of dissolved solids (salts) in the soil from tapwater and fertilizer solutions, which limits a plant's ability to absorb water – so watering in sips simply moves us to the other horn of a dilemma. It creates another problem that requires resolution. Better, would be to simply adopt a soil that drains well enough to allow watering to beyond the saturation point, so we're flushing the soil of accumulating dissolved solids whenever we water; this, w/o the plant being forced to pay a tax in the form of reduced vitality, due to prolong periods of soil saturation. Sometimes, though, that's not a course we can immediately steer, which makes controlling how often we water a very important factor. In many cases, we can judge whether or not a planting needs watering by hefting the pot. This is especially true if the pot is made from light material, like plastic, but doesn't work (as) well when the pot is made from heavier material, like clay, or when the size/weight of the pot precludes grabbing it with one hand to judge its weight and gauge the need for water. The advice to water when the top inch or two of the soil is dry is almost always counter-productive. Fingers stuck an inch or two into the soil work ok for shallow pots, but not for deep pots. Deep pots might have 3 or more inches of soil that feels totally dry, while the lower several inches of the soil is 100% saturated. Obviously, the lack of oxygen in the root zone situation can wreak havoc with root health and cause loss of a very notable measure of your plant's potential. Inexpensive watering meters don't even measure moisture levels, they measure electrical conductivity. Clean the tip and insert it into a cup of distilled water and witness the fact it reads 'DRY'. One of the most reliable methods of checking a planting's need for water is using a 'tell'. You can use a bamboo skewer in a pinch, but a wooden dowel rod of about 5/16” (75-85mm) would work better. They usually come 48” (120cm) long and can usually be cut in half and serve as a pair. Sharpen all 4 ends in a pencil sharpener and slightly blunt the tip so it's about the diameter of the head on a straight pin. Push the wooden tell deep into the soil. Don't worry, it won't harm the root system. If the plant is quite root-bound, you might need to try several places until you find one where you can push it all the way to the pot's bottom. Leave it a few seconds, then withdraw it and inspect the tip for moisture. For most plantings, withhold water until the tell comes out dry or nearly so. If you see signs of wilting, adjust the interval between waterings so drought stress isn't a recurring issue. Al

Jordan, you'll have a better response on the House plant forum.

Okay two major problems I'm seeing: Brown spots on leaves that fell off look to be due to overwatering, a lack of air in the soil and/or salt buildup. The reddish spots underneath your leaves are called oedema and can be caused by a number of factors, most often by excessive water retention in the soil (which I think is mostly your problem). Additionally, Fiddles don't really like to be moved, so while giving them optimal light is great, changing their living conditions so frequently can cause them to drop leaves like this. If you can move it outside for the summer, they tend to thrive. Some people even keep them in full southern sun and they love it. Even if you end up burning the leaves and they fall off, they will bud right back out with leaves that are suited to that amount of sun. I put mine right into morning sun today and kind of expect to lose some leaves to this but they'll bud right back out. If I've learned anything from all my research and time with my plant it's this: they are pretty hardy and will bounce back. I don't think you'll lose the plant if correct your watering issue! Here's a link to a post with the holy grail of information about every problem you think you could possibly have. There are several posts about the spots your seeing on your leaves and a guy named Al has some awesome advice I would recommend reading! The post is huge but I would suggest just scrolling down looking for pictures of whatever problem you're experiencing and read responses (that's what I did and I learned A LOT!
