Ok I've been having a problem with tissue paper thin leaves for about three harvests now. I think I'm doing everything right but no matter what, about a week or two into bloom ALL! my plants start getting thin yellow and eventually burnt crispy leaves. The ones that don't die are stunted. Although I've had several mothers I've had the same strain for about three years now. In the begging everything was great, it was almost too! easy to grow big bushes of buds, now I just cant get it right. A friend suggested I start over from seed because my strain might be getting weak. Another friend told me that strains never get weak. I don't know? Whats the longest you've kept a strain before starting from seed again? Does cloning generation after generation eventually make your plants weaker?
P.S. Three years ago I started from clones so there is no telling what generation I actually started with.
