First off, I would bet that your figs are in containers. If so, it probably means that they are not getting enough water. If they are in the ground, I would be surprised they would have early signs of going dormant since you are in Zone 7 like me.
I would make sure that your trees are watered well while in the pots. I know it's cooling off now but you need to continue watering them otherwise they will stress from the heat and the figs won't ripen well.

their in the ground and i have a sprinkler system which waters them appx 10 minutes a day should i increase the time?

If you lived in the humid southeast I would suspect overwatering. You mentioned that these leaves are both small and near the bottom of the tree - if the rest of the tree is doing alright, the leaves not curling or changing color, then I doubt you have any real problem. Check your soil and see if it's really wet, figs don't like wet roots.

Agree with Elder's advice. Sorry I jumped the gun. Most of my figs are in pots and I'm experiencing the same problem only from underwatering.
