It delivers only phosphorus and potassium, the two nutrients plants demand most when rooting, flowering and ripening fruit. No nitrogen, no chloride, no sodium, and a low salt index, which means a powerful bloom boost with less risk of leaf burn or salt build-up.\u003c\/p\u003e\n\u003ch3\u003eGuaranteed analysis\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eElement\u003c\/th\u003e\n\u003cth\u003eg\/kg\u003c\/th\u003e\n\u003cth\u003e%\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhosphorus (P)\u003c\/td\u003e\n\u003ctd\u003e220 g\/kg\u003c\/td\u003e\n\u003ctd\u003e22%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePotassium (K)\u003c\/td\u003e\n\u003ctd\u003e280 g\/kg\u003c\/td\u003e\n\u003ctd\u003e28%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eContains no nitrogen (N).
