I have tested faded and green side by side on a few strains and agree with this for sure.
Healthy green ripening plants make more canabanoids too. And have better more lasting and complex highs.
The time to cure out the chlorophyll for smooth taste seems more strain dependent than anything else. Fruity indicas taste good sooner than peppery haze in my experience.
But fading the plant can have it smooth enough for sale maybe a week sooner. It's because of the chlorophyll not the nutrients. But it will never taste as strong or as good as a non faded one cured properly.
All of the techniques we argue on forums have their place. It's mis information and lack of knowledge that causes the this or that argument.
I may leach a pot before harvest. If I overfed the plant and there is too much salt buildup.
Or I may feed heavier than average to the end. It depends on the plant and the individual grow.
Wouldn't it be better for us all to discuss why we do things? And learn to agree on common plant science before we make up or follow myths?
That is why I studied and read years before actually trying to grow. And had a successful perpetual garden for almost 3 years before ever posting any info here.
I read all the threads too but 7 years later the same arguments and misinformation is still posted every day.
I think we may be high.
