hey there, welcome to the board.

My 2nd grow was kinda like that. By the time harvest came around damn near every leaf had yellowed, shriveled and fallen off the plant. I spent a fair amount of time trying to diagnose it. What i finally settled on was bad roots. It was an ebb and flow system and for some reason the roots didn't survive...which to me meant the plant wasn't getting fed, which meant the plant was using all the stored energy in the leaves to try and stay alive...therefore when the leaves were used up they yellowed and fell off.

I don't know your setup or anything, but check your roots. if they are brown and shriveled i bet you the plants are not getting fed and doing their damnedest to stay alive. sucks.

hope that helps. do the troubleshooting form and we'll be right back with ya.

thanks

ps - here's my thread about the aforementioned plants: http://boards.cannabis.com/plant-pro...ml#post1857359

And here's a pic about a week before harvest. You can bet that all the leaves you see in the pic fell off by then.
