General Hydroponics FloraMicro

You should switch to the Hardwater formula if your tap water exceeds 200 ppm or contains more than 70 ppm of calcium. Using the standard formula in these conditions can lead to nutrient lockout or toxicity, as your water is already providing a high baseline of minerals.

Yes, you can blend the two formulas to create a custom nutrient profile that perfectly matches your specific water quality. This is a common technique for growers whose water quality fluctuates or falls somewhere between the ideal ranges for the standard and hard water versions.

Hardwater FloraMicro has an NPK ratio of 5-0-1, which is identical to the original formula. The primary difference lies in the micronutrient profile and calcium levels, which are adjusted to prevent nutrient imbalances when starting with mineral-heavy water.

Not necessarily. While this formula is specifically balanced for high-calcium water, some fast-growing or heavy-feeding plants may still require additional calcium and magnesium supplementation depending on your specific crop and growth stage.

Yes, it is designed for use in all hydroponic systems, including deep water culture, drip irrigation, and coco coir setups. It remains fully liquid and highly soluble, ensuring it won't clog your irrigation lines or emitters.
