Northen lite not looking well!

This is my northen lite that I put into flowering back 25 days ago,,,I was away in hospital for a few days and left the watering and feeding to someone else to do,,when I came back I noticed that this one plant did not need any water, so I waited a couple of days for the soil to dry up but noticed yesterday the pot is soaked in water,someone over watered it,I stick my finger a few inches in the pot and it feels like mud in there,,Now my plant has been looking quite weak, the tips of leaves are curling,,,should I transplant this one in dryer soil? Is it too late to save it? Attachment 282408Attachment 282409

I took care of the problem,,,I cut it down and thrashed it last night,,I found out it had been overwatered,,,after digging around the soil a bit,,there was an awful smell coming out of the pot,,the smell was unbearable ,,it really smelled like swamp water,,anyways when I pulled it out of the pot all the roots were turning black,,,time to go,,,,
