Description
Phosphorus, Magnesium and Sulphur for a Stronger Flowering Stage
SUPERthrive Mag-Pro is a nutritional supplement with an NPK of 2-15-4, rich in phosphorus, magnesium and sulphur. It is designed to prevent and correct deficiencies in those three elements and to promote earlier, heavier flowering: bigger, more colourful and more fragrant blooms, with flavour lifted through greater production of essential oils and flavonoids. Mag-Pro suits soil and every growing medium, by hand-watering, irrigation or as an additive in hydroponic solutions.
Key Benefits
- NPK 2-15-4 – a phosphorus-rich booster that sits on top of your base feed.
- Magnesium and sulphur – the two elements most often short in heavy flowering.
- Earlier, heavier flowering – bigger, more vibrant blooms.
- Flavour and aroma – supports essential oil and flavonoid production.
- Any medium – soil, coco and hydroponics.
- Won’t clog drippers – safe in automated irrigation.
Yellowing Between the Veins in Flower?
Interveinal yellowing on older leaves during flowering is a classic sign of magnesium deficiency, and a crop short of phosphorus and sulphur flowers late and light. Mag-Pro tops up all three alongside your base nutrient, keeping leaves green and plants feeding hard through the most demanding weeks.
How to Use
SUPERthrive’s feed chart, per 10 litres of water:
- Recirculating hydro: 7ml in veg week 3, 13ml in veg week 4; 13ml in flower weeks 1–4, 26ml in week 5, 13ml in weeks 6–7, 7ml in week 8
- Coco and run-to-waste: 7ml in veg weeks 3–4; 7ml in flower weeks 1–2, 13ml in weeks 3–4, 26ml in week 5, 13ml in week 6, 7ml in weeks 7–8
- Soil and compost: 6ml in veg weeks 3–4; 6ml in flower weeks 1–2, 12ml in weeks 3–4, 24ml in week 5, 12ml in week 6, 6ml in weeks 7–8
- Add each SUPERthrive product to the water separately and stir well between additions; never mix the concentrates together. If you use Pro-TeKt, it goes in first.
- Check and adjust pH last: 5.5–6.5 for hydro and coco, 6.2–7.0 for soil and compost.
- In hard water areas cut every mineral nutrient by 1–2ml per 10L to keep the final EC below 2.5 mS/cm.
