In soil or coco with Berkana at correct EC: calcium deficiency is rare. Check pH first before adding anything.<\/div>\n<\/div>\n<div class=\"jp-faq-item\">\n<button class=\"jp-faq-q\">Do I need Uruz with Berkana?<\/button><\/p>\n<div class=\"jp-faq-a\">Most growers do not. Uruz is specifically for hydroponics, aeroponics, and mistponics at high intensity where calcium demand exceeds what Berkana alone provides.<\/div>\n<\/div>\n<div class=\"jp-faq-item\">\n<button class=\"jp-faq-q\">Can I add too much calcium?<\/button><\/p>\n<div class=\"jp-faq-a\">Yes. Excess calcium locks out magnesium, potassium, and iron.
