Where standard Horti Cal carries 14% nitrogen for the full cycle, Late Cal delivers highly bioavailable calcium and essential micronutrients with no nitrogen at all — so plants keep strong cell structure and heavy bulking through the final weeks without the risk of excess leafy growth. It's a fully water-soluble dry formula from Green Planet's professional Horti Commercial Line, in a 1.13 kg pouch.\u003c\/p\u003e\n\n\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
