Hey mate. Looking at your diary.
You are not near the end of flowering yet. You need to add or if no def signs keep it going for at least another 3-5 weeks. Depending on your strain and other factors. But your buds got mucu more swelling mate. And ripening to do.
As for flushing on the last week just feed heavy water. To prolong the drying period (as the plant will have high water content) longer dry better quality.
