If you're watering it a little everyday then the roots may not have grown that deep. You need to up the amount and wait til it's bone dry, sounds like you may be root locked, then again you're watering it a LOT so it could just be over watered. Like that guy said a lil over half a liter every 3 days and you're giving it that every morning. Let her dry out before watering again she's drooping like she's over watered.
