With out seeing the fig, I'd have to guess that the tree is showing stress from lack of moisture. I'd try deep watering the tree a couple of times a week and see if that helps.

I'm having the same problem with overwatering being the likely cause. It has rained here nearly every day since May and one of my potted figs has basically said enough. I drilled a couple more holes into the pot and have added a wick to help pull away some of the excess moisture, but I'm going to have to wait and see how it goes. I repotted many of my figs into a more easily draining mixture, but I figured I'd leave the three largest alone (as I had repotted them last summer) but I never considered I'd see as much rain as we've had this spring/summer. ~Chills

Al helped me greatly when I was having so much trouble with my young fig trees this spring. I originally used regular garden soil (bagged) and there was no drainage, then, I repotted them in MG Moisture Control potting soil and that was even worse because the soil stayed sodden. Al suggested I put wicks in one of the holes in the bottoms of the pots, so I did and that even did no good, so I got some Fafard Professional Potting Mix and repotted them again and used the wicks while the plants were little, but pulled them from the pots when the root ball developed. The wicks are made from string mop refills and can be found at Wal-Mart and they are RAYON, not cotton. You need to read the package to make sure they are rayon. You cut one to a shorter length and can feed it up into the pot if the plant is already in the pot. I used a screwdriver and wet the wick and then folded a little of the top over for the screwdriver to grab onto and then stuck it up into the hole in the bottom of the pots. The rayon doesn't stay soggy, but provides a pathway for perched water to find its way out of the bottom of the pot and into the ground. Hope that's not confusing. Perched water is water that sits in the bottom of the pot and never drains out, which will end up killing the little roots and then the plant. Did I get that right, Al, if you see this? :) noss

I think this brown spots is rust infection. The Fungi is very bad this year not only for figs but for host of trees. I noticed some brown spots on my fig trees too and I an spraying copper. ALTHOUGH THE RUST IS NOT HATMFULL TO THE FIG FRUIT my trees are very green and healthy and I hate rust. You can remove the infected leaves and dispose away. Your tree is not doing good in the ground because the root got a chuck it will do good next next year.
