Vivosun Nutrients Base A \u0026amp; B simplifies the foundation to two bottles, used in equal amounts from seedling to harvest. Base A (4-0-1) supplies nitrate nitrogen and 4.5% calcium. Base B (1-4-2) delivers phosphate, potash, magnesium, and molybdenum. Together they provide the essential macro and micronutrients plants need through vegetative growth and flowering.\u003c\/p\u003e\n\u003cp\u003eCalcium and phosphate can react with each other in concentrated form, which is why Vivosun keeps them in separate bottles. Add Base A to your water first, then Base B, and stir thoroughly. Never mix the two concentrates directly together. The label's feeding schedule scales from 1–3 ml\/gal per part for seedlings and clones up to 9–14 ml\/gal during early flower, then tapers to 7–10 ml\/gal for flowering weeks 5–8.\u003c\/p\u003e\n\u003cp\u003eVivosun Base A \u0026amp; B is 100% water-soluble and works in soil, hydroponics, and coco coir. It suits vegetables, herbs, flowers, ornamentals, and other plants, and is designed to be used every time you water. If plants show signs of stress, or you're growing in very bright, hot, or dry conditions, reduce nutrient strength. The bundle is available in 8 oz, 32 oz (1 quart), and 1 gallon sizes, with one bottle of each part.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cstyle\u003e\n  .image-gallery-container{max-width:1240px;margin:20px auto;}\n  .image-gallery{display:grid;grid-template-columns:repeat(2,1fr);gap:1rem;}\n  .gallery-item{aspect-ratio:1;overflow:hidden;border-radius:8px;}\n  .gallery-item img{width:100%;height:100%;object-fit:cover;display:block;transition:transform 0.3s ease;}\n  .gallery-item:hover img{transform:scale(1.05);}\n  @media (max-width:768px){\n    .image-gallery{display:flex;overflow-x:auto;scroll-snap-type:x mandatory;-webkit-overflow-scrolling:touch;gap:0.75rem;}\n    .gallery-item{flex:0 0 85%;scroll-snap-align:center;}\n  }\n\u003c\/style\u003e\n\u003cdiv class=\"image-gallery-container\"\u003e\n\u003cdiv class=\"image-gallery\"\u003e\n\u003cdiv class=\"gallery-item\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1383\/1731\/files\/Nutrient_Base_A_B_Bundle_6.jpg?v=1790785668\" alt=\"Vivosun Nutrients Base A and Base B two-part liquid base nutrient bundle\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"gallery-item\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1383\/1731\/files\/Nutrient_Base_A_B_Bundle_4.jpg?v=1790785668\" alt=\"Vivosun Base A 4-0-1 and Base B 1-4-2 nutrients for vegetative and flowering stages\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"gallery-item\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1383\/1731\/files\/Nutrient_Base_A_B_Bundle_11.jpg?v=1790785668\" alt=\"Vivosun Base A and B nutrient feeding schedule for soil, hydroponics and coco\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"gallery-item\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1383\/1731\/files\/Nutrient_Base_A_B_Bundle_5.jpg?v=1790785668\" alt=\"Vivosun two-part base nutrients in 8 oz, 32 oz and 1 gallon sizes\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cstyle\u003e\n  .features-grid-container{display:flex;flex-wrap:wrap;justify-content:center;gap:1rem;padding:2rem 0;font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;margin:0 auto;max-width:1240px;}\n  .feature-card{background-color:transparent;padding:1.5rem;border-radius:8px;text-align:center;flex:0 1 240px;box-sizing:border-box;}\n\u003c\/style\u003e\n\u003cdiv class=\"features-grid-container\"\u003e\n\u003cdiv class=\"feature-card\"\u003e\n\u003cspan style=\"font-size: 2.5em;
