Is Epsom salt good for plants?
Epsom salt helps improve flower blooming and enhances a plant’s green color. It can even help plants grow bushier. Epsom salt is made up of hydrated magnesium sulfate (magnesium and sulfur), which is important to healthy plant growth.
Can too much nitrogen cause yellow leaves?
If you use a high-nitrogen fertilizer mixture, you also increase the soil’s mineral salts; excessive elemental nitrogen takes water away from the plant while leaving the salts behind. As a result, the leaves take on a burnt look from dehydration. Leaf edges become yellow or brown and wilt.
What are the symptoms of iron deficiency in plants?

What causes nitrogen deficiency in plants?
N lack relates to the soil type and is typical for sandy and well-drained soils with fast nutrient leaching. Excessive irrigation and heavy rains cause nitrogen deficiency due to overwatering. A lack of soil moisture tampers with the absorption of water-soluble nutrients by plant roots.
