She's looking good and frosty - and her foliage is starting to fade - all of which indicates that her time is coming. I also base this on the color of the pistils which are turning a nice color as well... I would give her maybe another week and then flush - and prepare for trim jail!
Nice job... (and NEXT grow, start a diary so that when problems/concerns/questions come up, we'll have all the information we need to help you!)
Good luck!
