no temperature changes result in magenta leaves..... not yellow... I'm not here to argue man... i know what I'm talking about. to each his own.
yes PLANTS leaves are green at harvest like tomatoes and others... ANY cannabis plant harvested with GREEN fan leaves is harvested too early... ALL FAN LEAVES IN SOME WAY YELLOW AT END FLOWER... some more than others but all FAN LEAVES YELLOW
we shall have to agree to disagree, as they say, your mileage may vary
the leaves on my plants stay green because i supply adequate nutes until harvest
i do not harvest plants early
i do not agree that harvesting plants when all the leaves turn yellow is a good idea, for those that keep their plants healthy they would be
taking their plants way past maturity waiting for all the leaves to turn yellow
i have grown 12 to 16 week sativas that finish mostly green
i have rejuvenated the same plant multiple times keeping the plant green over several months through multiple harvests
