Hey Wayne!

This is actually hard to answer, we don't know what size pot its in, the plant size, the strain, and we can't actually see pictures.

The reason it's hard to answer is because some strains when close to finishing will soak up all the nutrients from the leaves, turning them all, and eventually killing them off. For the strains that do this, it's a good thing, because all those nutrients are going straight to the buds to swell them up. So use photobucket or another image sharing site, give us some general pictures, and a few closeups - Tell us about the pot size your using, and any strain knowledge you have. Also give us a few shots of the buds that are forming or have formed, because at this point the bud health is more important than the leaves.

Have you started using bootstrap molasses in your water yet?

I'll give the support and help I can, but really do need more info before I can help.
