Discontinue one week prior to harvest. Massive and PK Spike are alternatives, not additions to each other. GreenPlanet: “Maintain the nutrient solution pH between 5.8 – 6.3 at all times. Keep the nutrient solution temperature between 18 – 22°C.” Ensure a minimum 10% runoff in run-to-waste systems. GreenPlanet's EC targets are calculated on RO water — tap water raises the stated EC, so reduce the dose to match. Check pH and EC after mixing.\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Green Planet","offers":[{"title":"1L","offer_id":53496873287946,"sku":"HCS-B2-002-01","price":16.9,"currency_code":"GBP","in_stock":true},{"title":"4L","offer_id":53496873320714,"sku":"HCS-B2-002-02","price":64.9,"currency_code":"GBP","in_stock":true},{"title":"10L","offer_id":53496873353482,"sku":"HCS-B2-002-03","price":98.9,"currency_code":"GBP","in_stock":true},{"title":"23L","offer_id":53496873386250,"sku":"HCS-B2-002-04","price":159.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/nutrients-green-planet-massive-37841285677271.jpg?v=1786221392","url":"https:\/\/hydrocropshop.co.uk\/products\/green-planet-massive","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
