I only use nutes for the first 7 weeks. I wait to feed until it has been in flower for a week.Are you doing away with nutes the last week or so? If not you will get a super harsh smoke with a little chemical taste... The last week they only need water.
Sorry reading this post made me think of this: [video=youtube;0W6JgnCFezo]http://www.youtube.com/watch?v=0W6JgnCFezo[/video]Yes it does. you want that chloryphyl to break down by properly curing them. are your buds super harsh to smoke?
