Collection: Organic Nutrients and Additives

Organic and organic-leaning feeds for growers avoiding synthetic salts: BioBizz's full line (Bio Grow, Bio Bloom, Fish Mix, Bio Heaven, Top-Max, Acti-Vera and their own Bio CalMag and Bio pH Down), Advanced Nutrients' Iguana Juice Bloom, and Plant Magic's Organic Grow 5-3-3 and Organic Bloom 3-5-4. Organic feeds are gentler but slower to show correction than synthetic ones — give changes a week before adjusting further.
