If you don't go by ppm... then I would suggest using OG Raskals sched- super simple: 1 capful of Big Bloom and 1 1/2 Capful of Tiger Bloom per 1 gallon of water. Adjust as needed, I found I use a bit more Big Bloom- just pick up a gallon of Ozarka Spring water add the capfuls and use that for every watering until gallon is done. Just make sure you at your ideal PH once done mixing...which is why I use Ozarka
