This strain got a flowering period of 70 days so 10 weeks. They still need to flower for 7 more weeks till they are ready for harvest. I think that you misunderstood it and that you tought that the full grow would take 10 weeks. But the time given by the seed company is only the flowering time. And it will start counting from the moment that you see the first pistils (white hairs). Your plant just finished early flowering and still got to mid and late flowering. Download the feedchart from advanced nutrients and continue from mid flowering.
