Flushed one week. One to go till cut n dry. The 300 PPM is that I use White vinegar to lower my PH and it is around 250-300 PPM, plus water isn't 0 PPM, Normally mines around 50 - 80 PPM. Plants basically flushed just need to go on another 5 days-ish before cutting.
@Grow3rPT, I quite like this pairing of MAC + Wedding Cake. It only smells (heavy) if you either spray it with water or you actually touch the buds (do that guaranteed sticky hands and stinky). It has a gorgeous earthy smell but with a massive hint of sweetness that you cannot quite put your finger on which sweet it smells like I go with Candy Floss -ish.
