Not any way to say what you did. My guess is that you had a hermie plant that popped a couple male pods, and released pollen all over the plant. If this happens; I just finish the plants dry them and smoke them. As mentioned; Not ooptimum, but still worth it especially if you were into the 6th week. I would not have pulled them until they were finished though (Especially Sativa). If they were an indica pheno; You might have some decent smoke. Good Luck
