The cannabis plant requires a genetic foundation to produce the pigment anthocyanin (which creates the purple color) true.
The "candy striping" or purple streaking, is not just a cosmetic genetic choice the plant is telling you she is short of oxygen in rootzones and/or carbon. There is a scarcity of oxygen. 43% of your plants dry matter is comprised of oxygen molecules attached to carbon skeletons.
Genetics determine how easily a cultivar triggers this response, but the environment is the switch that turns the stripes on.
Elite, not quite. Nothing grown in Dave smiths basement using synthetic delivery, the guy who knows nothing of autophagy, nitrogen sinking, complex profiles of the elite nature only express when the plant goes to war. You re lucky to even hit 1g/w given your setup.
Certainly don't mind new growers learning and growing.
Knowing is better than abject guessing.
