How to tell real purple weed from fake

Ace of spades was one of the most purple plants I have grown. While I didn't care too much for that pheno there's still some people in my circle who love it and all they grow.

You mean this glow in the dark neon pink weed I have might not be real? SHIT!

Wait, if the plant glows does that mean it will never truly enter the dark period, and thus stay vegetative indefinitely?

Or maybe it's for easy identification out doors so they can eradicate it.

I don't like it.

First time posting on this thread, sorry if i sound like a noob but i actually disagree with this post. I have actually tested this out on my own buds and so to say, the purple comes right off. No dyes added, nothing. Its all grown with GH nutes. I do not even know how to put food coloring on it to make it that ridiculously purple.

Your beating a dead horse? Last post on this thread was 5 months ago!
