So your telling me a plant exhibits no yellowing while that far into flowering? I'm not rude or disrespectful but I'm going to challenge you on what is there not to go there about. Yellowing of leaves and shift of the darker bronzing is due to the leaf drying out after it's been sucked of the nutrients ( if flowering was fresh I'd have to say it's a deficiency or error in soil ). Other chances of yellowing occur from nitrogen toxicity or deficiency. But those are for earlier stages of plant life later on a deficiency is expected. The main reason why I Implied his plants looked normal was because he is almost done and ready for harvest. I've had quite the messages from well known growers and have asked my fair share of questions to update my knowledge. I'm no where near pro, but I still can provide a hell of a plant.
