Brown yellow leaves?

Hello, I doubt it too.. I would say you have a calcium deficiency. This immobile micronutrient helps maintain cell walls. Calcium deficiencies can cause new growth (roots or young leaves) to form incorrectly and become distorted. Prevention • Add dolomite/lime to your growing substrate. • A pH of 6.2 will provide a better environment for calcium absorption. • Add plenty of eggshells to your organic compost. • Start a worm farm! Vermicompost offers a ton of nutrients, including calcium. Solutions • Apply a cal-mag booster. • Increase or decrease the pH to reach 6.2. • Add a teaspoon of hydrated lime to 4 liters of water and use the solution to water your plants. And if it’s magnesium This mineral is at the heart of the chlorophyll molecule and allows it to absorb light. Magnesium deficiency will give a scorched appearance to the lower growths. The leaves will yellow, dry out, and eventually turn brown. Prevention • Include dolomite lime in your growing substrate. • Use a compost rich in manure. • Maintain a good pH balance. Solutions • Flush your substrate with water at a pH of 6.0 if it is inadequate. • Epsom salts are a source of magnesium. Add 1–2 teaspoons of Epsom salts to about 4 liters of water and apply until symptoms resolve.
