nitrogen fertilizers?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Nitrogen fertilizers are <strong>fertilizers or supplements<\/strong> whose main function is to <strong>provide nitrogen to the plant<\/strong>. This nutrient is one of the essential <strong>macronutrients<\/strong> along with phosphorus and potassium, which is why it usually appears on labels as the first number in the <strong>NPK<\/strong> value.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"450\" src=\"https:\/\/www.growbarato.net\/blog\/wp-content\/uploads\/2026\/07\/fertilizantes-nitrogeno.jpg\" alt=\"A growing marijuana plant with healthy green leaves after the application of nitrogen fertilizers\" class=\"wp-image-236806\" srcset=\"https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2026\/07\/fertilizantes-nitrogeno.jpg 1000w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2026\/07\/fertilizantes-nitrogeno-300x135.jpg 300w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2026\/07\/fertilizantes-nitrogeno-768x346.jpg 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n<\/div>\n\n\n<p>For example, in a fertilizer with an NPK formula of 4-2-3, the first number indicates the proportion of nitrogen. The higher that number, the more nitrogen the product will have compared to the other nutrients.<\/p>\n\n\n\n<p>In <strong>marijuana cultivation<\/strong>, nitrogen is especially related to <strong>vegetative growth<\/strong>. That is, the phase in which the plant develops <strong>leaves, branches, stems<\/strong>, and structure before focusing its energy on flower formation. For this reason, it is especially necessary to use nitrogen fertilizers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Nitrogen_fertilizers_how_do_they_help_your_plants_grow\"><\/span>Nitrogen fertilizers: how do they help your plants grow?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><a href=\"https:\/\/www.frontiersin.org\/journals\/plant-science\/articles\/10.3389\/fpls.2020.572293\/full\" target=\"_blank\" rel=\"noopener\">Nitrogen<\/a> participates in <strong>basic processes for plant development<\/strong>. A plant with an adequate supply of nitrogen fertilizer usually shows <strong>more vigorous growth<\/strong>, healthy green leaves, and a greater capacity to form a strong structure.<\/p>\n\n\n\n<p>In cannabis, nitrogen fertilizers mainly help to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Promote the <strong>growth of leaves and branches<\/strong>.<\/li>\n\n\n\n<li>Maintain good photosynthetic activity.<\/li>\n\n\n\n<li>Improve <strong>stem development<\/strong> and structure.<\/li>\n\n\n\n<li>Support the <strong>recovery of plants<\/strong> weakened by deficiency.<\/li>\n\n\n\n<li>Maintain mother plants or crops with long vegetative phases.<\/li>\n<\/ul>\n\n\n\n<p>This does not mean that the more nitrogen fertilizer you use, the better the plant will grow. <strong>An excess can be just as problematic as a deficiency<\/strong>, especially if the use of nitrogen fertilizers continues into the flowering stage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"When_to_use_nitrogen_fertilizers_for_cannabis\"><\/span>When to use nitrogen fertilizers for cannabis?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Nitrogen fertilizers are used primarily <strong>during the growth phase<\/strong>. At this time, the plant needs to form a good vegetative base before moving on to flowering, so nitrogen plays a more important role than in later stages.<\/p>\n\n\n\n<p>Nitrogen fertilizers can also be useful <strong>in other specific cases<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>After rooting<\/strong> clones, when they start to grow vigorously.<\/li>\n\n\n\n<li>In <strong>young plants<\/strong> that show slow development.<\/li>\n\n\n\n<li>In mother plants that are kept in the growth phase for a long time.<\/li>\n\n\n\n<li>In crops where <strong>clear symptoms of nitrogen deficiency<\/strong> are detected.<\/li>\n\n\n\n<li>In <strong>long vegetative phases<\/strong>, where the plant consumes more nutrients.<\/li>\n<\/ul>\n\n\n\n<p>On the other hand, during advanced flowering, it is advisable to be more careful with nitrogen fertilizers. In that stage, the plant usually needs nutrition more oriented toward flower development, so <strong>an excess of nitrogen can affect the balance of the crop<\/strong>.<\/p>\n\n\n\n<fieldset style=\"border: 2px solid #00A48C; background-color: #F9F9F9; padding: 20px; margin: 30px 0; border-radius: 8px; font-family: Arial, Helvetica, sans-serif; color: #333;\">\n  <legend style=\"font-size: 2.3rem; font-weight: bold; color: #00A48C; padding: 0 10px; margin-top: 15px;\">\n    Key idea&#x1f4a1;\n  <\/legend>\n  <p style=\"font-size: 2.2rem; line-height: 1.6; margin: 10px 0;\">\n    Nitrogen is more important during growth than during advanced flowering. \n  <\/p>\n<\/fieldset>\n\n\n\n<p>Using a nitrogen fertilizer at the right time helps achieve strong plants; abusing it can cause problems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_do_you_know_if_a_plant_needs_nitrogen_fertilizers\"><\/span>How do you know if a plant needs nitrogen fertilizers?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>A nitrogen deficiency usually starts in the older or lower leaves of the plant.

The difference is that their cycle is shorter, so there is less room to correct excesses. That is why, with autos, it is especially important not to over-fertilize and to adjust the dose well from the beginning.\n      <\/div>\n    <\/div>\n  <\/div>\n  <div itemscope=\"\" itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n    <h3 itemprop=\"name\" class=\"accordion-titulo\" style=\"width: 100% !important;\"><span class=\"ez-toc-section\" id=\"What_do_I_do_if_I_have_used_too_much_nitrogen\"><\/span>What do I do if I have used too much nitrogen?\n<span class=\"toggle-icon\"><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n    <div class=\"accordion-content\" itemscope=\"\" itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n      <div itemprop=\"text\">\nThe first thing is to stop adding nitrogen-rich products and observe the plant&#8217;s evolution.
