N-P-K, or the (0.05-0-0.10) nutrient ratio, stands for Nitrogen (N), Phosphorus (P), and Potassium (or potash)(K). More nitrogen is used during the vegetative stage, and the plant loves phosphorus during flowering. You'll need a fertilizer with a higher phosphorus level to produce heavy buds. Go with an organic fertilizer if you can, but even a Miracle Grow bloom booster would work better than what you have now...and I'm not a fan of chemical fertilizers at all. I like using bat guano, though there are also a lot of other & more water soluble nutrients on the market.
Mr. Clandestine Reviewed by Mr. Clandestine on . Fertilizer Question. Is is ok for me to use a rooting solution such as Earth Juice Rootstock as a fertilizer for flowering? I know that Earth Juice has bloom solution but i was just wondering if i could get away with using my cloning solution the nutrient ratio is 0.05-0-0.10, it's all organic, but I assume that the zero in the middle represents a nutrient that is not present. Is this going to be a problem? Rating: 5
