Well in a way your way wrong, its actually about 6.5 weeks old now maybe 7 but my timer has gone all funny on me so it went from 18/6 where it was to 24/0 at my house. plus we put it in a stupidly large pot with some home made soil. it was john innings something, with some locally produce compost, some other stuff, general purpose soil & perlite. and all these together with the pot and the light sent the plant into full on veg growth.
its getting silly now iv already bent it pretty much in half and im having to tie it down constantly, its going nuts
I think prob another 5 weeks left because its not flowering at the minute just vegging

with lots of little buds from before it was potted on.
iv cut the light down to 12/12 for a couple of days to see if i can get it to stop growing and start producing flowers
Anyway i'l post a few pics in a min.
