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
JackdaWack Reviewed by JackdaWack on . 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? Rating: 5
