I dont know about the buds, but it makes sense. Ya can bring purple color out of many strains (even if they werent purp b4), by lowerin day temps to low 70's and night temps in the low 60's
yea. smells normal. you should try it with a small branch at harvest. just put it in a cup of water with lots of food coloring, then back under light for 24 hours
it will not absorb through the roots, as they said above FDD did it and it works with a fresh cutting and tastes charcoally and bites your throught, he tried the watering idea apprently it doesnt work.
