Grow More is a line of professional-grade, water-soluble fertilizers with specific formulations for every stage of plant development. For pepper growers, their product range covers seedling nutrition through fruit ripening, with options for bloom boosting, calcium supplementation, and micronutrient correction. This guide covers which products to use when, how to mix them, and how to apply them by growing style.
Quick Reference
- Seedlings: 20-20-20 at 1/4–1/2 tsp/gal, weekly or bi-weekly
- Vegetative growth: 30-10-10 at 1 tsp/gal weekly
- Pre-bloom: switch to 10-55-10 as branching begins
- Fruit fill and ripening: 5-10-40 every 7–10 days
- Flush containers every 3–4 weeks to prevent salt buildup
What Peppers Need at Each Stage
Pepper nutrition requirements shift significantly across the growth cycle. Seedlings need mild, balanced feeding. Vegetative growth calls for nitrogen emphasis. At the transition to flowering, phosphorus and potassium become more important. During fruit fill and ripening, potassium drives size, flavor, and color development.
Grow More Products by Growth Stage
| Product (N-P-K) | Best Used During | Nutrient Emphasis | Application Notes |
| 20-20-20 | Seedling & Transplant | Balanced all-purpose | Use at 1/4–1/2 tsp/gal weekly or bi-weekly. |
| 30-10-10 | Early Vegetative | High Nitrogen | Stimulates leaf growth in early stage. Avoid overuse. |
| 10-55-10 | Pre-bloom / Flower Initiation | High Phosphorus | Used before and at the start of flowering. |
| 0-50-30 | Flowering / Early Fruiting | Extreme P-K Boost | Powerful bloom booster. Use cautiously. |
| 5-10-40 | Fruit Fill & Ripening | High Potassium | Supports large, flavorful fruit. Use every 7–10 days. |
| 6-30-30 | Bloom Support | High P-K | Use during peak flower and early fruit set. |
| Seaweed Extract | All stages | Micronutrients & Hormones | Improves stress tolerance and overall vigor. |
| Calcium Nitrate | Fruit Set | Calcium & Nitrate N | Prevents blossom end rot. Use as supplement. |
| Iron Chelate 6% | As needed | Iron (Fe) | Corrects yellowing from iron deficiency. |
| Magnesium Sulfate | As needed | Magnesium + Sulfur | Supports chlorophyll and enzyme function. |
Mixing and Dilution Guidelines
Start seedlings at 1/4 tsp per gallon of 20-20-20. For vegetative growth, move to 1 tsp/gal of 30-10-10 weekly. Begin bloom formulations (10-55-10 or 0-50-30) once plants start to branch or show pre-flower buds. Transition to 5-10-40 or 6-30-30 as fruit sets, and continue through ripening. Always dissolve powders completely before applying. Flush every 3–4 weeks to prevent salt buildup, especially in containers and greenhouses. For foliar feeding, dilute to 1/4–1/2 strength and apply at dusk or dawn.
Product Compatibility and Nutrient Management
Most Grow More products mix well with each other and standard supplements. Seaweed extract and calcium nitrate can both be used alongside nutrient mixes, but calcium nitrate should not be combined with phosphates in the same tank—they react and precipitate out. Iron chelate and magnesium sulfate work best as corrective foliar treatments. Always pH-test your solution and target 5.8–6.5 for optimal nutrient uptake.
Application by Growing Style
Containers: Flush with plain water every two weeks to clear salt buildup. Feed at lower doses more frequently—weekly is better than bi-weekly in containers.
Greenhouses: Monitor EC (electrical conductivity) regularly. Mix in large batches and pre-dissolve powders before adding to the reservoir.
Field and garden beds: Water deeply after feeding to push nutrients into the root zone and prevent leaf burn. Supplement with compost tea or organic matter when possible to support soil biology.
Grower’s Takeaway
- Match the formulation to the growth stage—switching from high-N to high-P/K at first flower is the single most impactful adjustment
- Never mix calcium nitrate with phosphate products in the same tank
- Flush containers every 3–4 weeks; salt buildup silently limits nutrient uptake
- Foliar feeding with iron chelate or magnesium sulfate corrects deficiencies faster than soil application
