Check your planet's cargo, and see how much supply they have available.

If you sucked them dry when you arrived, you could either move the ships, or order them to load (under cargo) supplies from the planet.

The resupply depot will distribute a small number of supplies as noted before, each turn to ships anywhere in the system. It will also push an unlimited number of supplies to ships entering and/or leaving the hex. (Limited only by the planetary storage amount)
