Blueberry OG kush bloom time and harvest

Its suppose to be 8-10 weeks, but that is just flowering time not including the vegetative and seedling stage, so if the plant was in veg for 4 weeks plus the 10 weeks for flowering means you should have harvested at 14 weeks so you harvested a month and a half too early which is the reason for the low potency. Hopefully, I answered your question and remember Happy Growing and Free your mind one puff at a time.
