Have you changed your nutes routine? If not, your plant may be showing that its growth is nearing the end of its life. Mrs_Larimar told me that it's all about the appearance of your plant that decides if it's finished.
The leaves should be discolored (autumn leaves), the pistils should be brown/orange, and the trichomes cloudy. I hope this helps you in your fantastic grow.
