Q.I have Ficus trees inside an atrium that are dropping and or not producing new leaves.
There are 12 trees altogether and they are approximately 15′ tall. They are potted in planters that are 7′ in diameter and 4′ deep. They are a focal point in our building. We are treating them for fungus and low iron. 11 have responded well and are putting out new leaves. A few of them are developing fungus spots on the new leaves. One tree in particular has maybe 30-40 leaves and isn’t putting out new ones. I plan to continue treating for fungus but is there anything I can do to cause this one to begin producing leaves. We have been treating for about 6 months and this one tree isn’t doing anything.

You may want to repot this tree with fresh soil and fertilize it. You also may want to place it in another location - apparently it's not happy with where it currently sits.
Another possibility is that it's suffering from a fungus that's different from the ones you're treating for. You may want to take a sample from the tree to your local garden center or extension service for advice: https://www.gardeningknowhow.com/extension-search?ip=79102&radius=20&services_search_action=search&submit=Search
