Looks good man, but it looks 2-3 weeks away to me. You can probably start flushing if you want, but you have a lot of white hairs. Have you checked the trichromes? How long have you been flowering? What makes you think it's one week away?
What strain is it? Give it a while til the hairs start to go brown...2-3 weeks, check the trichomes with a magnifying glass - mostly cloudy with some amber is a good time but personally I like to get more amber if I can, the BEST method is to watch the plant itself...keep feeding, then when the fan leaves suddenly start going yellow start the 2 week flush coz its nearly ready, eventually ALL the fan leaves will go yellow and die after some flushing - don't panic, just keep flushing til 2 weeks has gone by then chop-chop!
looking nice but not impressive, sorry, but still, nice job..u still have cuople of weeks to go, maybe 3, but it can go up to 4...Good luck with your grow...
