Witch it correct, when it come to chlorophyll but not nitrogen, if your leaves, sugar leaves are green there's nitrogen in them leaves. Nitrogen and chlorophyll go hand and hand.
I dry as slow and long as possible on the cut branches still with the bud leaves intact. I shoot for ten days but never make it past 8 in my closet.
Then I trim off the bud leaves for infused coconut oil and tincture so I am not smoking them or any random loose buds that also go in the trim jars.
And I screen the weed during trimming to sift loose trichomes for hash.
We even jar cure the trim before use. You could smoke it and never suspect it is what it is.
I promise you all of this tested higher when medium green and healthy at harvest when I still supplied a dispensary and everyone noticed the better potency, smell and flavor.
I think you are here and know why I don't want to go back to the dispensary. I am sorry I never got to copy my lab results a few years ago. They were confiscated.
The plant is peaking when it is ready. Not dead. I like to see 100% cloudy trichomes. Or colorful on some sativa leaning strains. It uses nutrients til the day I cut. Like I said. I can see the ppm's from the soil runoff go down.
With growing different seeds every week in a staggered perpetual garden I tried many methods of all these arguments and other "advanced" techniques.
With the way I have learned to read plants taking care of them individually in a group for a few more years now every day is any sooner than the last watering or two of withholding nutes will result in pretty immediate deficiency. I have learned I don't want to see that.
A yellow harvest is not better in any way but to make quicker cash.
Our meds are healing my wife's internal cysts now. That did not happen back when I grew on schedules and flushed like a noob. Which I was.
