I would correct the pH now... otherwise, you're just letting her deal with the wrong pH for a longer period of time. The more the plant drinks, the faster the soil will dry out... if you had an incorrect pH, that probably caused her to stop drinking as much as she normally would have - BUT, it also depends a lot on the age of the plant. As they get into flower, they will require more and more water/nutes... if she's not that old, 4 days is what I would call about normal...
Good luck!
