As flowers set, uptake rates change fast and the solution starts swinging - and every swing outside the band means a group of nutrients briefly stops being available. Growers chase it with acid and alkali, which corrects the number but does nothing about the underlying instability. A buffer salt holds the solution steady between adjustments, so the plant gets uninterrupted access to what is already in the tank rather than a series of short lockouts nobody sees.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStart at half strength.\u003c\/strong\u003e The directions below are maximum strength and response varies between plant types -
