purple maxx

Hi everyone I just heard of a product known as purple maxx and was wondering if it would bring the blue and red hues out of my blue widow. Or is it like using molasses or something similar

I have a few friends that grow the purple and blues and was told that rather then using purple maxx they either drop the temp significantly the last 1-2 weeks or if thats not possible they simply grow over 1-1.5 weeks which also works. The 1 friend who grows purple cush told me that growing over nearly turns the entire plant purple.

It should work though seeing as most blue based plants had a purple plant in their genetic line to give them the blue. I have no clue what the ingredients are but was told first hand that the stuff does work.
