here's my next update. day 7 of flowering so i'm wondering when i'll start to notice buds appearing. i would love some feedback so please take a look and criticize! thanks! http://www.growkind.com/marijuana/gardens/2559/
you should start to notice developement within a week and by the third week they should have some nice little budsites starting to fill out a little. DOn't worry alot happens in 8+ weeks!
Looks good man! Those plants are really healthy and happy. I would suggest training them though. A 400w doesn't give enough light to reach the lower branches on these tall sativas. If you start training them now you should be able to maintain 3 to 3.5 feet in height through harvest. But that's just my opinion...
