Bloom A and B step down through flower, 14 to 13 to 8 to 4 mL\/gal. PK+ goes the other way: \u003cstrong\u003e2 mL\/gal\u003c\/strong\u003e in early flower, \u003cstrong\u003e4\u003c\/strong\u003e at mid, \u003cstrong\u003e5\u003c\/strong\u003e in late, and \u003cstrong\u003e7 mL\/gal\u003c\/strong\u003e at finish. By week nine it is the largest single input in the tank. That crossover is the whole idea. Phosphorus, potassium and sulfur keep arriving while nitrogen walks down, so the plant gets the signal to stop building and start filling. The analysis is \u003cstrong\u003e0-4-6\u003c\/strong\u003e with \u003cstrong\u003e1% combined sulfur\u003c\/strong\u003e and no nitrogen whatsoever. That is what lets you raise it late without undoing the taper you spent eight weeks setting up.\u003c\/p\u003e\n\u003ch2\u003eA Zero-Nitrogen Bloom Supplement With Two Ingredients\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eRead the derived-from line and there are exactly two entries: \u003cstrong\u003emonopotassium phosphate\u003c\/strong\u003e and \u003cstrong\u003epotassium sulfate\u003c\/strong\u003e. Nothing else. That matters more than it sounds. Plenty of bulking products lean on chloride salts to force a fade, and chloride accumulates in a recirculating system in a way sulfate does not. Both salts are highly soluble, so PK+ runs through drip and fertigation panels without the settling you get from heavier bloom boosters. It is not tied to the FloraPro base either. It layers onto FloraPro Powders or another brand's line just as readily. That makes it a reasonable first trial if you are curious about the program but not ready to change base nutrients.
