Yeah, I can believe that's true. I've always done it the way I've described above though, which results in roughly 5%. After flowering there are very few healthy fan leaves on most of my weed plants, especially in the bottom half, so that becomes an issue. Perhaps next time, on plants that I want to reveg, I will give them a little N during flowering in the hopes they won't eat the leaves so much. Never thought about trying that before. Could this be bad?
