@ChitownCannaChica,
If you want purple colour, you can try stressing it with cold, It's a fairly common mutation from the plant experiencing frost.. I wouldn't recommend it, as you might end up killing the plant, get mold, or other problems..
@TheWeedPimp,
You probably shouldn't blame the breeder with bad genetics, with an "I think", my friend. ^_^
It have nothing to do with the genes.. The purple colour is a stress thing in this case. As I could read in your diary, it didn't have a particularly good start to life, but as you only started the diary after it started flowering, I don't know what you did with the plant before that.. However, it's clear that it was under a lot of stress during that time, and the low stress training you did, didn't help her calm down either.
You ended up with a pretty good result tho, considering. So I wouldn't feel that bad about it. ^_^
