Welcome to the waiting game LOL!
Root suckers can draw some energy from plants, but that's not what's happening to your fig.
They start out as a little grain of rice, then grow rapidly for several weeks.
Then they stay like that from 2 to 3 months, and you get to watch them mope.
There's nothing you can do but wait.
Suddenly that little fig (if it doesn't drop - search Smyrna, San Pedro, O'rourke) will change color slightly, then grow a little more, then droop.
When you're sure it's ripe, net it, and wait another 2 days to pick it if you can take the torture!
Figs are at the peak of ripeness if you pluck them and there's no latex in the stem.
Congratulations on your first fig. Do you know what variety you have there?
