The harvest window was calculated to start next week. However, I've been monitoring the trichomes under a microscope and the majority of top buds had a nice mix of amber triches, I had to begin harvesting a week early.
This week I began harvesting the topmost buds only in order to allow the lower ones to continue to develop and mature. We certainly had a few hearty colas, with a number of well defined buds throughout all three plants. Next week we will harvest the remaining as initially estimated.
