You still only use it for a week per cycle, but you no longer have to ration the bottle.\u003c\/p\u003e\n\u003ch3\u003eWhat it does\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCanna PK 13\/14\u003c\/strong\u003e delivers extra \u003cstrong\u003ephosphorus and potassium\u003c\/strong\u003e (NPK 0-13-14) in a highly concentrated liquid. Plants need a lot of both when flowers start to fill out, and a short, well-timed dose supports bigger flower clusters and denser fruit. It works in soil, coco and hydro alongside your normal base nutrients.\u003c\/p\u003e\n\u003ch3\u003eHow far 1 L goes\u003c\/h3\u003e\n\u003cp\u003eAt the maximum dose of 1.5 ml\/L, a litre treats roughly 665 L of nutrient solution. With a 100 L reservoir, one PK week needs 150 ml, so you get four or more cycles from a single bottle.\u003c\/p\u003e\n\u003ch3\u003eWhen to give it\u003c\/h3\u003e\n\u003cp\u003eThe window is about seven days at 50–60% of the flowering time. For a plant that flowers 8 weeks, aim for week 5 to 6; for a 10-week plant, shift it to around week 6. Mix it into your regular feed rather than replacing anything.\u003c\/p\u003e\n\u003cp\u003eAfter adding PK, measure the pH again, because potassium lowers it. Signs of calcium or magnesium deficiency mean you should cut back the dose next time.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents:\u003c\/strong\u003e 1 L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNutrients:\u003c\/strong\u003e phosphorus (P), potassium (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDosage:\u003c\/strong\u003e max. 1.5 ml\/L (15 ml per 10 L)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Canna","offers":[{"title":"Default Title","offer_id":58748426551640,"sku":"C8CNA77099","price":13.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/9584\/8792\/files\/0a111b4cf3b42573d2e30558909b907b.jpg?v=1791823618","url":"https:\/\/growdealz.com\/products\/canna-pk-13-14-1-l","provider":"Growdealz","version":"1.0","type":"link"}
