very strange i have a quicksilver auto flower plant going right now and it's maybe 3 feet tall and maybe 3 months old already. no signs of buds at all, but definately female...i hold my breath waiting for her clock to start up and produce something.....if not . i might try to clone her branches and throw em under a 400 hps......
My latest research (been all day in weed-forums today, and went to the local growshop who sold me those seeds) found that sometimes... just some times, the autoflowering gen in the seeds is not triggered. Its a matter of genetics, it seems. And makes a long-last auto flower, just like your 3 month old quicksilver and my 4 month old lowryder 2.
Nothing to worry though, since they will surely bud, just a little later...
It still sucks, I know. I would be stoned at this very moment if my first LR2 behave how she supposed to. Lets hope this second one does.
The guy from the grow shop also adviced to feed the new lowryder 2 with flowering nutes to get the best off her. I've been doing so with the old one, and I must say she's coming good. So, for anyone following this thread, if any, I will be feeding the girl with bio-flower flowring very soon...
cheers!
