- Only one of the fan leaves has been showed a kind of one of the Nutrients Toxicity signs, or its might be a sign of Magnesium Deficiencies.
Because as what the teachers mentioned:
“Calcium deficiencies tend to manifest in the growth of younger leaves; calcium ions are immobile in the plant, so a deficiency in calcium will affect the younger leaves.”
“Magnesium deficiencies tend to present themselves in older leaves as magnesium is a mobile nutrient. The plant will direct what little magnesium it has to new growth, leaving older leaves magnesium deficient.”
