I don't use a pen.. I just use ferts at 1/4 the dose.. I still flush them a week before harvest.. Something bout the taste of it. The ferts that is..Weed tastes better when this procedure is done.. Just that odd-ball plant with necrosis,with me too! I've tried to help her to no avail.Peace to ya Hemp!
