If your plant has turned purple it means that it has a nitrogen or phosphorous deficiency. This is not a good thing, unless your are growing a purple strain and it is meant to be purple. First off make sure that your plant has a pH of between 5 and 7 this can be a crucial reason why it is not getting the proper nutrients. Probably the easiest way to fix this is to buy a fertilizer with the macro-nutrients nitrogen, phophorous and Potassium (just to be safe). Try a hydroponics store. Also, avoid giving the plant too much fertilizer, this can burn them.
