It means you have some sugar left in your cider. We will need more information to tell you more.
What was your starting gravity? (Yep, we know you just got your hydro, so skip this for now.)
What is your batch made from? Fresh pressed cider, store bought apple juice, frozen concentrate? Did you add sugar or honey?
What yeast did you use?
Did you direct pitch the yeast, or did you make a starter?
Have you added any yeast nutrients?
What is your fermentation temps.
All I can tell you right now is that you have some apple flavored liquid with a SG of 1.048.
