Now thats what I'm talking about. Good to c u sled :)Excellent topic. I test brix with a refractometer. In addition to brix levels, also test for calcium, potassium, and ph. Helps get a better picture of what is going down. I use soil testing along with sap testing to determine if what you are doing is working or not.
For example: Test brix of one plant. Do a foliar spray or drench. Then re-test the brix again 2 hours later. Did you get a positive plant response or not?
If you got a positive response than apply to entire crop.
Hey Mama I'm not sure I agree completely with your take on cannabis fade i.e. autumn colors. More of what determines fade or autumn colors is a compound called "anthocyanins" and is found in most c3 plants however it is a genetic thing and that's why some strains purported to be granddaddy purps show some green phenos with no purple due to the level of anthocyanin in the gene pool. Not all cannabis strains or phenos contain enough anthocyanin to give us that gorgeous autumn fade.I don't actually test for brix levels but I keep an eye on fall colors. I know that fall colors (especially red) are due to high brix levels so I look for those plants. It takes a lot of sugar to make the color red.
I don't DO anything except keep my N in check. I give them just enough to keep them green. Nothing kills brix levels faster than too much nitrates.
I guess what I was trying to say was , that as brix is the measure of sugar content, at what point is the optimal range for cannabis and is there a point where it can be detrimental to our plant ? Could too high a brix level have the consequences of though yielding great, reducing quality ?Jumpin Cactus is right, it has to have the genetics to allow color production in the first place. And genetics can have "levels" of more or less color.
MidwestToker is also right, a glucose molecule is required for production of anthocyanin. Plants with more glucose will produce more red/purple pigment.
Hey Rancho, I'm working on a purple unicorn myself. I've locked down the purple leaves, purple calyxes and I just found some with purple pistils. Gotta get it all together in 1 plant. Maybe 2-3 more generations should do it.
that is a good question, of which I am not qualified to answer.From my understanding of Anthocyanin, a glucose molecule is required for production of anthocyanin. So why wouldn't brix levels have direct correlation with anthocyanin production.

I'm not qualified either ! I just go by the 40+ years of growing experience and the few purple strains that I've grown or created. Although they have bag appeal, I feel they are lacking in something.that is a good question, of which I am not qualified to answer.
Here is some of my collection.Heres a good example of green plant/purple plant.These 2 are sisters grown right next to each other they are pretty much the same,height,branching,flower size,smell fed the same things one faded in colors one didnt.The green one has purple stems thats it the other is loaded with colors
I would have to agree as I have found that as you said purps are pretty with awesome bag appeal at times the purps can lack in potency when compared to the greener phenos from the same runs. Seems the greens always dominate in the potency side. Would be nice to know and understand why that would be......???I'm not qualified either !
