The first mistake you made was soaking your mix. I wouldn't do that, personally.
Adding perlite ... I don't think it will help. It's just gonna soak up the water, and that water will still be in the bag, really.
After two weeks, it's remotely possible that you could have roots popping, re-bagging could be dangerous. You're better just to leave the lid off your container for a few hours a day to allow moisture to escape. That's about the best I can offer.
