How do you achieve these kind of leaves? ( Yellow, Purple)

[IndustrialHemp]

Hey guys, So I just saw this Instagram post and I'm blown away by the phenotype colours! I know that leaves can change to purple, and etc but never like that. How does this happen? How does one breed to get those pheno's? I heard somewhere it has to do with temperature for some strains, and just genetics in general.

Thanks

temperature, and leeching of nitrogen from leaves during flushing phase

and the genetics of course

I think it has more to do with genetics than temperature, although temperature can cause or be a catalyst for coloration. It's not necessarily caused by removing this nutrient or that nutrient, however depriving the plant of certain nutrients (specifically nitrogen) will cause this to happen. Plants naturally fade at the end of their life cycle as long as they are healthy, regardless of remaining nutrients. Their colors vary from plain yellow to blue, purple and red. Achieving certain colors is a matter of selecting plants that display the colors you want and using those plants in your crosses.

My last 2 weeks of flower (I go 69 days from flip to chop), I drop my temps and lower my co2. 2nd last week is 75* lights on and 70* lights off and 500ppm. Last week is 70* lights on and 65* lights off and 500ppm.

Every run, and nearly all 15 strains do this

Organics, just add water.

cold temps and ion fed gardens pictures are all about a decade old

I don't grow with bottles anymore

always preferred this look tbh

Assuming that archives grow room is well climate controlled (which is likely because they've been growing for a long time), it has more to do with nutrition. The instagram picture you posted is probably high phosphorus antagonizing magnesium. They might run normal temps with botanicare the majority of the grow where the Mg def sets it, then drop temps the last week to get more color which is when P would become less available.

Another good example is weirds last picture, which is a K deficiency. Could be antagonized by other nutrients but most likely just low K in the mix to start, especially if its peat based.

Why would you want that?

or a matter of letting off of the earth juice teas at the end of maturation, back in the day we called it fading

fed nothing but EJ grow, bloom and catalyst

no gas or climate control

No longer on the bottle even though it was organic

the room they where in

 

[Weird]

even with my organic soil I endeavor to have my plants feed off of their own nutrient stores come harvest

I find weed that has feed of it's own stores burns smoother and with less heat, tobacco manufacturers have studied the nuances of how minerals in tobacco effect the properties of smoke.

Posted a bunch of them some time ago under a diff nick.

Put your ph under 5.5 or over 7 will lock out nutes like that... The darker colours like that are usually low ph.... High ph generally lightens the leaves and gets more pinkish hues...

Cold and over saturation also will do the same trick but can be bad for roots or soil if your recycling ect.

Weird, when I first started growing that is how I approached drying, slow and steady like tobacco. Some other growers I knew were speed drying to sell their crop and it didn't lead to good smoke.

One thing I've thought about quite a bit is that plants can still be fed until the end of the grow and not have it adversely affect the smoke if they are able to use the nutrients. I say feed but what I mean is amend the soil the right way and feed little nudges of stuff like aminos, gypsum, small doses of micro sulfates, etc. The opposite of this is over feeding nitrates and the plant not being able to turn that N into chlorophyll or protein. Higher brix with that really cloudy line and then a good 8-10 day dry minimum is what I'm aiming for.

Just the couple "fully flushed" + gens.

This one have a little bit of BB blood, enough to give colors.


This one not (skunks hybrid):


Both flushed to the bone.

 

[Florere]

Still no answer.
So again, why would you want this?

Hmmm, new account with link to seedbank in the first post and doesn't reply at all.
Curious indeed.
