I Know your supposed to flush 2 weeks before harvest but how do you know for sure. I don't have a magnifying glass or any of the usual tools growers use but I notice on some of the buds the white hairs are starting to turn browner. Here are some pics. I know the leaves are yellowing and it's a small plant. The soil is bad and had a buddy take care of her over spring break. Regardless the buds smell great and the leaves are covered. Thanks guys.
