Using Potassium permanganate?

I have heard if you apply potassium permanganate into the water you used to feed your cannabis plants that it will increase the purple content of your buds. Is this true? If so does it effect the plant at all other then color?

On another note i was wondering if anyone could answer these questions for me.

Best soil to use?
Best first time grow strain? (I am not stupid, i would like to grow something i can truly be proud of)
Nutrients? What should i use to increase health and growth?
Best place to buy seeds?
Also recommend amount of light/watt ratio for 10 plants

Cheers

Crazyy......I can barely spell it. I thought it said pomegranate. What I know is that plants can be "shocked purple" . If you notice, most deep purple strains originated in the far east, in harsher climates...I could only assume its the shock. Basically, "In the beginning..." there was a plant, she was a nice green happy plant...innocent...fresh to the world. Then the cold fall and harsh winter came along, and turned the innocent green sweetheart of a plant into some crazy Supa Crip purple plant from all the stress and temperature fluctuations. The end. And it was then implanted into the genes of new generations to turn purple. As the chlorophyl breaks down, and if strong anthocyan pigment genes are present in the plant, a red purple or orange start to show through. kinda like layers of tint....i think but don't quote me. I would assume :P
On a real note though. You ultimately control what you give your plant,
But the plant does have to have it in its genes, no matter how dominant. Unfortunately I don't think its like sticking a stick of celery in a glass of cool aid. I know from first hand, (not bragging it was a 1 plant closet grow hahaha) and other friends. You can shock a plant purple in some cases....but it does have to have the purple in its veins. Kinda like people who are predominantly one race, but way back in the blood line there was a completely different race thrown into the family. So to answer your question....its.........You can shock it purple with temperature fluctuations and odd lighting for a day or 2....I just wouldnt trust any chemical that I can barely spell on my girls :P

Now I helped you.....tell me about tissue cultures or tell a pro to message me......I must know about this amazing science....You can grow in thousands of identicle baby girls in a few petri dishes

I wish i could help you on your tissue culture question but i simply cant. I will do some research as i am enlightened by your post.
I am sure you have done your fair share of research but nothing better then multiple people in search of an answer. Message me back if you hear anything from a professional!

Cheers

For plants that have the "Purple Gene" the easiest way to turn them is to ice their roots after you flush them... (I.E. about a week or 2 before harvest)...

The cold is what triggers most outside plants to turn purple.

Also, to learn Tissue Culture, I would start with edible mushrooms. It's a very easy way to get some of the science down, but maybe not the details. (My bet is that the solution for plants is different than the solution used to grow mushrooms (mycelium)

Why do u want the plant to be purple? I mean its just a phenotype, has nothing to do with anything worth while. If u really want a purple plant grow one with the gene, Like purple urkle or something like that. If u over feed it with potassium it may turn a bit purple, I seem to have that issue all the time, for some reason my stems are always purple, and i get slight purple coloring in the buds. However, some strains under the same conditions just turned purple on the stems and nothing else. Temps never below 70
