I learned two things this season.

[Butcher Bob]

Hey Bob … how’s your venture in hydro coming along?

Nothin's goin right now. The buckit worked great, but I think Ima dirt kinda guy.

Were those 9 plants clones?

Yes, they're the real deal GSC that I've had my hands on for two years....if they were from seed no matter how stable I wouldn't have came to this conclusion as easy.

[jesus]

Well I figured they were but it didnt hurt to ask. I dont even know what GSC is.

[Jesús Malverde]

Until stable drug cannabis lines are developed (they exist for fiber cannabis already), all comparison testing will have to be done on cuttings from a single genetic source.

Yellow leaf = Plant sucking it's own chlorophyll for one or many reasons
Purple leaf = Genetics or most often frozen plant sap

I'm not sure you could call it intelligence , but plants , like any other "units" blessed with the energy of life do find a way to adapt and survive there environment ... If you can "read" them , the more power to you ...

[Roots]

This is the reason for both yellowing and purpling of leafs in flower.

"decreasing light levels cause chlorophyll production to slow. However, the decomposition rate of chlorophyll remains constant, so the green color will fade from the leaves. At the same time, anthocyanin production in leaves increases, in response to surging sugar concentrations"

[Sconeofark]

But these go to eleven.



This one up here is not losing chlorophyll at this point, but the leaves are turning a deep purple as it flowers.



Here, where the leaves are yellowing in late flower.

The purple is genetic in these, and in the leaves it usually stops right where the trichs stop.

i remember when i visited whatpot
he was new to growing outdoors upnorth and his genetics wernt well suited to the climate
they had basically stopped flowering 3/5ths through and he was bummed
we waited another two weeks but finally started pulling them
could have been alot worse

a friend of his with sizable grow elsewhere had stashed a few plants with him for insurance
that guys plants finished great!


the flowers were fat and a pale green
and all the fans and water leaves had yellowed just like scone's there

[Roots]

Scone's plant has purple flowers and sugar leaf but yellow fans....I'm talking about purple fans.

...more like what Bob posted.
