Interesting results, might need a side by side with control for better comparison.
Possible ingredients have me wondering too. @Cormoran
ABA maybe?
I have tried just about all the hormones but that one.
Maybe a mix of ABA and gibberelic acid.
There is some research out on the ABA but not much cannabis related.
ABA could help explain the color change.
ETH would do that too, but ETH does not come in a powder form that I know of.
But I never really checked.
