Fill your reservoir with the target volume of fresh water first, then add each part of Terra Aquatica Cal\/Mag Supplement separately, stirring between additions. If using a multi-part formula, add micro or Part A first, then grow or bloom, then any additives. Measure pH and EC after mixing and adjust to your target range — typically 5.8–6.2 pH and 1.4–2.2 EC for most crops.\u003c\/p\u003e\n\u003ch3\u003eWhat is the shelf life of Terra Aquatica Cal\/Mag Supplement?\u003c\/h3\u003e\n\u003cp\u003eUnopened, Terra Aquatica Cal\/Mag Supplement has a shelf life of 2 years when stored in a cool, dark location out of direct sunlight. Once opened, use within 12 months. Shake or stir well before each use as some formulations can settle. Do not freeze concentrated nutrients as this can cause precipitation of minerals that will not fully redissolve.\u003c\/p\u003e\n\u003ch3\u003eCan I use Terra Aquatica Cal\/Mag Supplement in soil as well as hydroponics?\u003c\/h3\u003e\n\u003cp\u003eTerra Aquatica Cal\/Mag Supplement is formulated for hydroponic systems but can be used for soil and coco growing at adjusted rates. Soil typically requires lower EC than hydro or coco as nutrients are buffered by the growing medium. Start at 50–70% of the recommended hydroponic dose when applying to soil and increase based on plant response.\u003c\/p\u003e\n\u003ch3\u003eHow do I dispose of leftover nutrient solution made with Terra Aquatica Cal\/Mag Supplement?\u003c\/h3\u003e\n\u003cp\u003eDilute spent nutrient solution with water and use it to water outdoor garden beds or lawns — it is an excellent fertiliser for outdoor plants. Avoid disposing of large volumes directly into storm drains. In residential situations, diluted nutrient runoff down a household drain is acceptable in small quantities.\u003c\/p\u003e\n\u003ch3\u003eDoes Terra Aquatica Cal\/Mag Supplement ship fast within Australia?\u003c\/h3\u003e\n\u003cp\u003eYes — Terra Aquatica Cal\/Mag Supplement ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.\u003c\/p\u003e","brand":"Terra Aquatica","offers":[{"title":"500ml","offer_id":43144238858303,"sku":null,"price":34.95,"currency_code":"AUD","in_stock":true},{"title":"1L","offer_id":43144238891071,"sku":null,"price":54.95,"currency_code":"AUD","in_stock":true},{"title":"5L","offer_id":43144238923839,"sku":null,"price":124.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/6898\/8479\/files\/CalMag-1L-1-2_1000x1000_Grey-copy-16.png?v=1776562691","url":"https:\/\/apexgrow.com.au\/products\/terra-aquatica-calmag-supplement-australia","provider":"Apex Grow","version":"1.0","type":"link"}
