Hello Almquista, at first Congrats to you homemeade fertilisers your plant looks great. If I look onto her i would say she can flower 3 more weeks, the Hairs of the Flowers are white, If they getOrange/brown your plant ends herLife cycle. If you see taht and the trichomes age changing you can start her to flush. In the comments i let you a link with pictures of ready to Harvest Plants and a link for flushing... Happy growing. and gotta read your diary complete iam nosey for your fertilisers.Hope you told us how you didi it
