At this stage of flowering if you only need to water every 3-4 days then I'd be looking at rootrot or some kind of fungus.
Usually every second day is just enough.
I would either chop her now or stop watering completely and let the plant dry out and die naturally. This creates stress causing the root system to push all resins into the plant to protect her from the environment.
Either way she is looking like a pretty good smoke.....
