Sensi Coco Bloom is formulated specifically for the bloom phase in coco coir, accounts for what coco already contains, and its pH Perfect technology genuinely removes the pH guesswork. Not cheap, but it works, and it's popular for a reason.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eAdvanced Nutrients Sensi Coco Bloom A\u0026amp;B is a \u003cstrong\u003etwo-part base nutrient designed specifically for the bloom phase in coco coir\u003c\/strong\u003e. This isn't a universal hydroponic formula adapted for coco — it's built from the ground up for how coco actually behaves. The formula raises calcium and magnesium (which coco binds) while lowering potassium (which coco already contains in abundance), preventing lock-out before it starts. It also includes triple chelation: calcium, magnesium, and iron all in forms your plants can actually absorb.\u003c\/p\u003e\n\u003cp\u003eThe real party trick is \u003cstrong\u003epH Perfect technology\u003c\/strong\u003e. As long as your water sits between 4.5 and 8.5 pH (basically everyone's water), the nutrient automatically buffers and stabilises it for you. No metering, no second-guessing, no mid-feed pH crashes. That's a genuine time-saver if you're using RO water or anything remotely soft.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eIn the coco-specific nutrient space, Sensi Coco Bloom occupies the premium-to-mid tier.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003evs General Hydroponics Flora + CalMag:\u003c\/strong\u003e GH is cheaper (often 30-50% less), works fine, but you're manually pH-ing and buying extra supplements. Sensi is convenience over lowest cost.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003evs Canna Coco A+B:\u003c\/strong\u003e Canna is similarly priced and equally proven. Both require supplemental cal-mag. Canna has a longer track record; Sensi has the iron chelation advantage and pH Perfect.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003evs Shogun Samurai Coco:\u003c\/strong\u003e Shogun's newer, includes yield-boosting additives, but hasn't got the decade-plus user base Sensi has.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvantage over all:\u003c\/strong\u003e Triple iron chelation — most coco nutrients skip iron entirely. That matters more than marketing suggests.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eUsage guidance\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBasic feeding protocol\u003c\/strong\u003e\u003cbr\u003eSensi Coco Bloom is a straightforward two-part system. Add Part A to your water first, mix well, then add Part B in equal volumes. The research suggests growers often run it at half strength (around 2mL\/L) to avoid nutrient burn, though Advanced Nutrients recommend 4mL\/L. Start conservative and adjust upwards if your plants are hungry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWith RO or soft water\u003c\/strong\u003e\u003cbr\u003eThis is where Sensi shines. If you're running reverse osmosis or rainwater, pH Perfect does the heavy lifting. No meter needed. Your water hits 4.5–8.5 pH, you mix the nutrients, and the formula self-regulates. This is not a gimmick — it genuinely works and removes one major stress point.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeeding schedule\u003c\/strong\u003e\u003cbr\u003eRun a daily feed until you see 25% runoff. Start cuttings and seedlings at low dose (1mL\/L or lower), gradually increase over the first 3 weeks, then run your working dose through bloom. Most users switch straight from veg to bloom without ramping down.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSupplementation\u003c\/strong\u003e\u003cbr\u003eEven with the enhanced calcium and magnesium, some growers still run supplemental cal-mag in coco — it's just how coco works. Don't assume you won't need it.

The triple chelation (especially iron) is a genuine advantage, the pH Perfect technology removes real stress, and thousands of UK coco growers rely on it season after season. It's not the cheapest nutrient on the shelf, but the concentrate goes a long way and the consistency is worth the outlay.\u003c\/p\u003e\n\u003cp\u003eOne thing worth knowing: Advanced Nutrients products run higher EC than some competitors because of how pH Perfect is formulated. If you've got soft water and you're tired of pH hunting, this is worth the investment. If you're budget-first and don't mind metering pH manually, General Hydroponics will save you money. But if precision and convenience matter more than lowest cost, this is solid kit. Good time to buy while this stock holds.\u003c\/p\u003e\n\u003c\/section\u003e","brand":"ADVANCED NUTRIENTS","offers":[{"title":"1 Litre","offer_id":47916266782890,"sku":"83558","price":22.49,"currency_code":"GBP","in_stock":false},{"title":"5 Litre","offer_id":47916266815658,"sku":"83559","price":89.99,"currency_code":"GBP","in_stock":true},{"title":"10 Litre","offer_id":47916266848426,"sku":"83361","price":184.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0053\/5540\/5400\/files\/83361_sensi_coco_bloom_10_litre_2.jpg?v=1769190314","url":"https:\/\/growershouse.co.uk\/products\/advanced-nutrients-sensi-coco-bloom-ab","provider":"Growers House ","version":"1.0","type":"link"}
