The leaf damage I have been getting has slowed down but it seems to be moving up the plant. The first leaves to show damage were in the top of the canopy and then on the larger fan leaves surrounding the main cola's. Now it is showing on the small leaves around the cola. New growth on the plant seems unaffected.

I am thinking of cutting feeding to alternate days, instead of 2 days on 1 day off. But my girls are 4 weeks 3 days into flower and I intend to stop feeding at the six week mark. So I am undecided.

anyway here's a pic...
