The Fix-It Guide for Your Plants
1. Nitrogen (Yellowing Lower Leaves)
Nitrogen is the "energy" nutrient. When it’s low, plants pull it from old leaves to feed the new ones.
The Quick Fix: Use a liquid fish emulsion or a high-nitrogen fertilizer.
The Long Game: Mix in well-rotted manure or blood meal into your soil.
2. Phosphorus (Purple Underneath)
Phosphorus is crucial for root development and blooms. Purple leaves mean the plant's metabolism is stalling.
The Quick Fix: Apply a liquid bone meal solution or a "bloom booster" fertilizer.
Pro Tip: Check your soil temp! If the soil is too cold, plants can't "eat" phosphorus even if it's there.
3. Potassium (Burnt Edges)
Think of potassium as the plant's immune system. Without it, the edges literally "scorch."
The Quick Fix: Add kelp meal or liquid seaweed extract.
The Long Game: Bury banana peels (chopped small) near the base of the plant or use wood ash in moderation.
4. Iron (Yellowing with Green Veins)
This is called "Interveinal Chlorosis." It’s often a pH issue rather than an iron shortage.
The Quick Fix: Use a chelated iron foliar spray for fast absorption.
The Long Game: Check your soil pH. If it's too alkaline (high pH), the plant can’t absorb iron. Add sulfur to lower the pH.
5. Sulfur (Pale New Growth)
Sulfur helps produce chlorophyll. Unlike nitrogen, this affects the newest leaves first.
The Quick Fix: Apply Epsom salts (Magnesium Sulfate) dissolved in water.
The Long Game: Use elemental sulfur or organic compost to build up long-term levels.
6. Calcium (Twisted New Tips)
Calcium builds the "bones" of the plant. Without it, new growth comes out deformed or "hooked."
The Quick Fix: A foliar spray of calcium nitrate.
The Long Game: Add crushed eggshells or garden lime to your soil.
Note: Ensure consistent watering! Calcium moves through the plant via water; if watering is erratic, the calcium can't reach the tips.
