hey boss you got great colas man. congrats. but regarding that leaf yellowing and brown spots and leaf-curl-- That may have been a magneasium deficiency. It is common during flowering. The yellowing and spots could be other things but what made me say Mag def- was the up-curl of those leaf tips; they say that they are praying for Magnesium. It often starts shortly after showing sex. Epsom salts or a proper additive Calcium & Magnesium are usually together. Good Luck and enjoy the buddage. :rastasmoke:
