i wouldn't rely on cloning after you flower but don't take my word for it...there are more people out there with experiance, you just have to wait for a more detailed response. good luck
first of all clone before flowering and it's unsure that there female unless feminized...i'd watch other threads for a bit and learn proper growing. check out Mr. Green on you tube...i don't agree with everything he does but it's good for starters(getting a general idea) if you follow to my post...
i recently tried growing and failed...first time for everything, this is my second shot but i believe i have nutrient burns... what can i do to prevent this or is it something other than a nutrient problem?
