通用水培植物生长肥 - 1 夸脱

Available Phosphate (P₂O₅) supports root development, energy transfer, and early structural growth by providing a form of phosphorus that plants can absorb and use quickly.

Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.

Total magnesium is important because magnesium powers chlorophyll and energy use, helping plants stay green, turn light into growth, and use other nutrients efficiently—and it’s unique because its problems often come from nutrient balance and uptake competition, not just a simple shortage.

Sulfur is important because plants need it to build key amino acids and proteins that drive real growth, strong structure, and efficient use of nitrogen, making it uniquely different from “look-alike” nutrients that may change leaf color without supporting the plant’s core building process.

Potassium carbonate is important because it can supply potassium for water movement, stress tolerance, and strong growth, while also pushing the root zone toward higher pH and alkalinity. It’s unique because it doesn’t just “feed potassium” like many other sources—it also changes solution chemistry, so it must be used carefully to avoid micronutrient lockout and calcium/magnesium imbalance.

Magnesium carbonate supplies magnesium for chlorophyll and steady energy production while also gently buffering acidic root zones, which makes it different from faster magnesium sources that mainly deliver quick soluble magnesium without stabilizing pH.

Magnesium phosphate supports chlorophyll-driven energy capture and phosphorus-driven energy movement, helping plants keep steady growth and stronger roots without the sharp swings of faster sources; it’s unique because it supplies both magnesium and phosphorus together in a typically slower-to-available form, so balance and root-zone access matter as much as the amount.

Magnesium sulfate supplies magnesium for chlorophyll and sugar movement plus sulfur for protein building, helping plants stay efficient and green during high-demand growth. It’s unique because it adds magnesium without extra nitrogen or calcium, so it corrects magnesium issues with fewer side effects when balance is the real goal.

Yes, it can if it pushes phosphorus too high or drives pH too low, because both conditions can reduce the plant’s ability to take up key micronutrients and calcium even when they’re present in the feed, which makes phosphoric acid uniquely powerful compared with slower, gentler phosphorus sources.

Potassium phosphate supplies both potassium and phosphorus, supporting root energy, nutrient transport, and flowering readiness when plants are actually limited by those nutrients. It’s unique because it delivers two major nutrients in a fast-available form, so it can correct a real PK bottleneck quickly, but it also requires careful use to avoid salt stress and nutrient imbalance.

Potassium sulfate is often preferred because it supplies potassium without added chloride and also provides sulfur, which supports protein-building and efficient nutrient use, making it a cleaner, balanced option when plants are sensitive to chloride or when you want potassium without pushing extra nitrogen or phosphorus.
