Changing Plant color

I was looking at some fertilisers on ebay and came across this, so I was wondering can I use it successfully for my plants to promote there colour, for example I was thinking if I used it perhaps it would give my berry bomb which is in early flower a more pronounced blue appearance, what u guys reckon

I've never seen anything like that. I'd suggest just trying to get your day and night temp down by 10-15f degrees. That will help bring the colors out and it's free!

What Cereal Box said!

OR

Get genetics that change colors regardless of temps!

purple maxx (humbolt nutes.) is supposed to change color.

59 F at night starting at flower. I probably started too early and got it too purple for most peoples liking. The clones I took had very little purple, so this is mostly just cold conditions.

not for me......theres the money shot baby o yea.....

Specific Hydrangeas change the color of their blooms depending on the acidity/alkalinity of the soil. Yes, Cannabis and Hydrangea are both plants but, this where any other similarity stops.
