Nutrient Deficiency - Houseplants

orchid nutrient deficiency

Symptoms of nutrient deficiency include yellow leaves and poor growth. Excessive fertilizer results in the buildup of salts and excessive, leggy growth with few or no flowers on flowering plants. Do not fertilize plants that are infested with insects or spider mites until the infestation is controlled. Excess fertilizer can aggravate insect and disease problems.
