WebJul 11, 2024 · Mirrors – If you’ve thought of using aluminum foil to reflect light onto your plants, the notion of employing a mirror probably wasn’t far behind. Depending on the backing materials involved (aluminum silver, gold), mirrors absorb some light wavelengths, while having the potential of disrupting the wavelengths plants need most. WebMolasses in the formula helps plants take up and use the potassium. PREVENTION: Even if you are using a high-potassium "bloom" fertilizer, the plants may not be absorbing it all because the pH of the nutrient solution is too high. For soil-grown plants, be sure the pH is 6.0 to 7.0 and for hydroponic crops keep the pH to 5.5. to 6.5. 9. Heat Stress
