Your starting water, EC, pH, growing media and chosen system can all affect what your plants need.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this episode, Sarah&#8217;s late arrival turns into no arrival at all, leaving Karlos to step in and take care of her plants. With nutrient brands picked from a hat, Karlos gets Plant Magic, Jasmine takes on House &amp; Garden and Ian demonstrates with Athena.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The maths causes problems on both sides, nutrients end up on Ian&#8217;s freshly painted walls, and Karlos makes a crucial mixing mistake. Once the chaos is over, Ian shows us how it should be done.<\/p>\n\n\n\n<div style=\"position: relative; width: 100%; padding-top: 56.25%;\">\n  <iframe src=\"https:\/\/www.youtube.com\/embed\/mxTMjDNti3M?rel=0\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\" style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%;\">\n  <\/iframe>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"gb-text episode-copy gb-text-ea168b84\">What You&#8217;ll Learn<\/h3>\n\n\n\n<p class=\"gb-text episode-copy\">This episode covers one of the most important parts of any grow environment:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Why you should test your starting water before adding nutrients<\/li>\n\n\n\n<li>What EC and pH tell you about your nutrient solution<\/li>\n\n\n\n<li>The correct way to mix nutrients and additives<\/li>\n\n\n\n<li>Why products should be added individually and mixed thoroughly<\/li>\n\n\n\n<li>How your growing system affects your nutrient regime<\/li>\n\n\n\n<li>Why recirculating systems need regular monitoring and fresh solution<\/li>\n\n\n\n<li>How growing media can affect the amount of nutrients you need<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"episode-content\">\n<h4 class=\"gb-text episode-copy gb-text-1badfd8f\">Understanding EC &amp; pH<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Before adding anything to your tank, Ian recommends testing the <strong>EC and pH of your starting water<\/strong>. This gives you a baseline and helps you understand what adjustments may be needed before feeding your plants.<\/p>\n<\/div>\n\n\n\n<div class=\"episode-content gb-element-c50dbd20\">\n<div class=\"wp-block-columns episode-column-blocks is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column has-base-background-color has-background is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"gb-text episode-copy gb-text-ffa6744b\">EC \u2013 How Much Food?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Ian describes EC as the <strong>food<\/strong>. Measuring EC gives you an indication of the strength of the nutrient solution you&#8217;re giving your plants.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your starting water matters too. If you&#8217;re beginning with hard water, for example, you may need a nutrient designed for those conditions and will need to adjust your feeding accordingly.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column has-base-background-color has-background is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"gb-text episode-copy gb-text-615b1baa\">pH \u2013 Is That Food Available?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">pH determines how available different nutrients are to the plant. If the pH moves outside the appropriate range, some nutrients may no longer be available for the plant to take up \u2014 even if they&#8217;re present in the solution.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That&#8217;s why getting the nutrients into the tank is only part of the job. You also need to check that the final solution is within the correct range for your grow.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"episode-content\">\n<h4 class=\"gb-text episode-copy gb-text-9ca45c29\">Ian\u2019s Guide to Nutrient Management<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">After watching Jasmine and Karlos tackle their nutrients, Ian steps in to show us how it should be done. From mixing nutrients in the right order to adjusting your regime for different growing systems and media, he breaks down the key things to consider when feeding your plants.<\/p>\n<\/div>\n\n\n\n<div class=\"episode-content gb-element-51e4ff4e\">\n<div class=\"wp-block-columns episode-column-blocks is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column has-contrast-3-background-color has-background is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"gb-text episode-copy gb-text-2e6d4fd5\">Mixing Nutrients Properly<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Ian starts by checking the EC and pH of his water before adding anything to the tank.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">He adds <strong>Athena B<\/strong> first and thoroughly mixes it into the water before adding the same amount of <strong>Athena A<\/strong> and stirring again. Only then does he retest the EC and pH and compare the results against the recommended feed chart.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The same principle applies when adding supplements: <strong>add one product at a time and mix thoroughly before adding the next.<\/strong> Combining concentrates before they&#8217;re properly diluted can cause problems \u2014 as Karlos discovers after putting root stim and enzyme into the same jug.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Make Adjustments Gradually<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> Ian moves on to his additives, he uses <strong>Cleanse<\/strong> to help with salt build-up, particularly useful with dripper systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After testing again, he uses <strong>Balance<\/strong> to adjust the pH. Rather than adding a large amount at once, Ian works gradually, adding a small amount and testing as he goes until he reaches the figures he&#8217;s looking for.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns episode-column-blocks is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column has-contrast-3-background-color has-background is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"gb-text episode-copy gb-text-e3119ac7\">Your Growing Method Matters<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Your nutrient regime needs to suit the way you&#8217;re growing. A recirculating flood and drain system, for example, needs to be managed differently from a run-to-waste dripper system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a recirculating system, plants continually take what they need from the nutrient solution. Over time, what&#8217;s left in the reservoir won&#8217;t necessarily contain the same balance of nutrients you started with.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ian recommends checking the girls&#8217; tanks around <strong>every three days<\/strong>, topping up with half-strength nutrients where required, and replacing the old solution with a completely fresh mix regularly rather than continually topping up the same tank.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column has-contrast-3-background-color has-background is-layout-flow wp-block-column-is-layout-flow\">\n<h4 class=\"gb-text episode-copy gb-text-48a5812b\">Don&#8217;t Forget Your Media<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Your growing media also needs to be considered when working out your nutrient regime.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An inert medium doesn&#8217;t provide nutrients itself, giving you control over everything the plant receives. A pre-fertilised medium already contains nutrients, so your feeding needs to account for what&#8217;s already available rather than simply adding a full nutrient regime on top.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"gb-element-c7831bf0 header-bg\">\n<h3 class=\"gb-text gb-text-f2c158c8 text-dark-green-bg\">Featured Products<\/h3>\n\n\n\n<div class=\"gb-element-0c97a4ed\">\n<div class=\"gb-element-23d8f1f8 product-container\" href=\"https:\/\/globalairsupplies.co.uk\/product-category\/filters\/\" target=\"_blank\" rel=\"noopener\">\n<a target=\"_blank\" rel=\"noopener\" href=\"https:\/\/globalairsupplies.co.uk\/product-category\/nutrients\/athena\/\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"1200\" class=\"gb-media-d7d3f041\" alt=\"\" title=\"EU-LQ-GWA-1G-F.-AB.png\" src=\"https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/05\/EU-LQ-GWA-1G-F.-AB.png.webp\" srcset=\"https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/05\/EU-LQ-GWA-1G-F.-AB.png.webp 1200w, https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/05\/EU-LQ-GWA-1G-F.-AB.png-300x300.webp 300w, https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/05\/EU-LQ-GWA-1G-F.-AB.png-1024x1024.webp 1024w, https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/05\/EU-LQ-GWA-1G-F.-AB.png-150x150.webp 150w, https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/05\/EU-LQ-GWA-1G-F.-AB.png-768x768.webp 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/a>\n\n\n\n<p class=\"gb-text gb-text-5c4ab8a2\">Athena Nutrients <\/p>\n<\/div>\n\n\n\n<div class=\"gb-element-913eae94 product-container\" href=\"https:\/\/globalairsupplies.co.uk\/product-category\/filters\/\" target=\"_blank\" rel=\"noopener\">\n<a target=\"_blank\" rel=\"noopener\" href=\"https:\/\/globalairsupplies.co.uk\/product-category\/nutrients\/house-garden-nutrients\/\"><img loading=\"lazy\" decoding=\"async\" width=\"1080\" height=\"1080\" class=\"gb-media-862a1775\" alt=\"\" title=\"HAG-RXLG1-UK-Flag\" src=\"https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/06\/HAG-RXLG1-UK-Flag.webp\" srcset=\"https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/06\/HAG-RXLG1-UK-Flag.webp 1080w, https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/06\/HAG-RXLG1-UK-Flag-300x300.webp 300w, https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/06\/HAG-RXLG1-UK-Flag-1024x1024.webp 1024w, https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/06\/HAG-RXLG1-UK-Flag-150x150.webp 150w, https:\/\/globalairsupplies.co.uk\/thegreatindoors\/wp-content\/uploads\/2026\/06\/HAG-RXLG1-UK-Flag-768x768.webp 768w\" sizes=\"auto, (max-width: 1080px) 100vw, 1080px\" \/><\/a>\n\n\n\n<p class=\"gb-text gb-text-ad44a18c\">House &amp;
