High HiddenMessage,
Yes too much water. You want the leaves to stand up proudly and not hanging like a claw. Just let the top soil dry out between waterings. You can lift up the pot once a day to get an indication howmuch water is still left inside the pot.
The colour looks good so you give the right amount of nutes.
You might also consider to defoliate the plant before going into flowering. By doing this you make sure that every budside gets enough (and equal amount) light.
Happy Growing!
