Hey bro! 👋 Your girl is having trouble absorbing nutrients from the soil, all because of overwatering! Your pot is 8.5 L, the maximum watering volume for your pot is 850ml. There's a rule for adult watering - 10% of the pot volume. Water the plant as needed, as soon as the top 2-3 centimeters of soil dries out. And considering the recommendation to water the plant daily, you need to reduce the watering volume until the surface of the soil starts to dry out within a day! 👌😇👍 Good luck, bro!
