General Hydroponics FloraPro Calcium + Micros | 25lbs

Calcium is critical for cell wall strength, root development, and nutrient transport, but it can't be mixed with phosphate or sulfate in concentrated form without causing precipitation. FloraPro Calcium + Micros is kept separate to maintain stability in your fertilizer injector tanks. This two-part approach ensures both calcium and other nutrients remain available without chemical reactions that would clog your system or create deficiencies.

Use FloraPro Calcium + Micros during every growth phase—it's the constant partner to the other FloraPro products. Pair it with FloraPro Grow during vegetative growth, then continue using it with FloraPro Bloom during early to mid-flowering, and finish with it alongside FloraPro Late Bloom. This ensures continuous calcium and micronutrient availability throughout the entire crop cycle.

Chelation binds micronutrients to organic molecules (EDTA, DTPA) that protect them from reacting with other elements in solution. This keeps iron, manganese, copper, and zinc plant-available across wider pH ranges and prevents them from precipitating out or becoming locked up. For commercial growers dealing with variable water chemistry, chelated micros ensure consistent nutrient uptake regardless of pH fluctuations.

While FloraPro Calcium + Micros is designed primarily for injection systems and root-zone feeding, it can be used as a foliar supplement in diluted form to address acute deficiencies. However, the primary application method is through your fertigation system where it provides consistent baseline nutrition. Always test foliar applications on a small area first and follow appropriate dilution guidelines.

Calcium deficiency appears as tip burn on new growth, blossom end rot in fruiting crops, or weak, brittle stems. Micronutrient deficiencies show as interveinal chlorosis (yellowing between leaf veins), stunted growth, or distorted new leaves. Using FloraPro Calcium + Micros as directed prevents these issues before they impact yields, which is far more effective than trying to correct deficiencies after they appear.

The 14% nitrogen comes from the calcium nitrate source material, which is the most stable and water-soluble form of calcium for injection systems. This nitrogen is factored into the FloraPro feed charts, so when you follow the recommended ratios, you're getting the correct total nitrogen levels from the combination of products. The dual benefit is that you're delivering both calcium and readily available nitrate nitrogen in one product.

No, never mix FloraPro Calcium + Micros with FloraPro Grow, FloraPro Bloom, or FloraPro Late Bloom in concentrated form. They must be kept in separate injector tanks and mixed only after dilution in your irrigation water. Mixing them concentrated will cause chemical reactions that create precipitates, clog your system, and make nutrients unavailable to plants. This is standard practice for all two-part commercial fertilizer systems.

No, FloraPro Calcium + Micros provides a complete micronutrient package designed to work with the FloraPro system. It contains all essential micros—iron, manganese, copper, zinc, boron, and molybdenum—fulfilling a role similar to General Hydroponics FloraMicro Nutrients but optimized for dry-salt commercial application. Adding additional micronutrient supplements can create toxic imbalances, so stick with the FloraPro system as designed.
