I dont think you harvested too early, but another week would have been good too. Plants and buds looking great. Your harvest depends on the high you like. I try to harvest by 10% amber trichomes and the rest mostly milky. When trichomes start to turn amber they actually turn from THC to CBN which will provide a more narcotic, couchlock high. Milky trichomes have the highest THC and clear will have a more racey high.
