What is causing this, how do i save them?
Very good observation on your part to notice that the water is coming out of drainage holes quicker than it should be.
This means that the soil had dried out in the container, shrinking and pulling away from the sides and leaving a gap. The water is not being absorbed by what is probably a peat-rich potting mix which repels water when dry, and the water you are pouring in is running down the gap and straight out.
You could keep pouring water in but you'll lose a lot just pouring out that way and that may not be ideal in a balcony situation --
You need to rehydrate the potting mix -- put the entire container in a larger tub to catch the water, keep adding until preferably at least 1/2 way up the sides, and let the water soak in from the bottom for 1/2 hr to 1 hr, then take it out of the tub let it drain.
