Why are some leaves darker green than others?
Young leaves have a lighter shade of green than matured and old leaves. Young leaves have yet to develop a fully functioning cell wall, and they can’t achieve photosynthesis as efficiently, both of which contribute to a lighter shade. As the leaves mature, they become darker green.
Why do most leaves appear green to the human eye?
Leaves appear green because of the chlorophyll they contain. Chlorophyll is the part of the leaf that uses carbon dioxide, sunlight and water to produce sugar.

Phosphorus deficiency tends to inhibit or prevent shoot growth. Leaves turn dark, dull, blue-green, and may become pale in severe deficiency. Reddish, reddish-violet, or violet color develops from increased anthocyanin synthesis.
Why are my plants going purple?
When you notice a plant with purple leaves rather than the normal green color, it is most likely due to a phosphorus deficiency. All plants need phosphorus (P) in order to create energy, sugars, and nucleic acids. Young plants are more likely to display signs of phosphorus deficiency than older plants.
How do they fix potassium deficiency in plants?
To correct a deficiency, spread organic mulch beneath plants and apply potassium fertilizer, preferably slow-release forms such as potassium silicate or sulfur- or polymer-coated potassium products. Potassium sulfate may be used, and potassium will be held by organic matter and clay particles.
What can you add to soil to increase phosphorus?
Adding green manure residues to soils can increase soil mineralization rates of phosphorus, but low concentrations in residues often won't meet crop demands.
How do I know if my plant needs nitrogen?
The first way is to take a look at the leaves. If the leaves are yellowing, this can be a sign of chlorosis — which could also be a sign that your plant is in need of nitrogen. Keep in mind, however, yellowing leaves can also indicate a few other issues (like overwatering). The second way is to perform a soil test.
How do I fix nitrogen deficiency?
Nitrogen deficiency can be corrected by applying either organic or inorganic fertilisers, but nitrate or ammonium-based fertilisers work the most quickly. Any general-purpose “grow” formula will usually provide enough nitrogen to correct major deficiencies.

Then, slight nitrogen deficiency changes with more severe symptoms: Larger leaves turn from pale-green to yellow and white.

Potassium deficiency
Potassium plays an important role in encouraging photosynthesis (the process of plants harnessing energy from the sun). Young tomatoes cannot absorb potassium as easily from cold soil as they can from warm soil. That's why, when planted in cold soil, their leaves may turn purple or yellow for a time.
Phosphorous deficiency
Tomato plants may also struggle to absorb phosphorous from cool and wet soil. While tomato leaves deficient in potassium may turn purple or yellow, phosphorus deficiency causes leaves to turn either purple or dark green. Tomato plants deficient in phosphorous may also experience stunted growth, necrotic spots on the leaves, and leaf cupping.
Burnt by light
Depending on the chosen grow light and the variety of tomatoes being grown from seed, leaves might turn red or purple, become pale and sunburned, or start to look curly and crispy. This can be due to seedlings getting close to the light or just getting too much light in general. 3
Viral infections
Some viral infections cause tomato leaves to roll, too. Whiteflies carry tomato yellow leaf curl virus that causes leaves to become cupped or pale green in color. Leaves may also have yellow edges or purplish veins on the underside. As a result, flower and fruit production can become stunted. 4
Insect infestation
Tiny insects known as Garden springtail ( Bourletiella hortensis) may injure small tomato seedlings. Garden springtails are extremely small, dark purple with yellow spots, wingless but using forked, tail-like appendages to project themselves into the air. They eat small holes in the leaves of small plants near the surface of the soil.
How to Prevent Tomato Leaves from Turning Purple
Planting tomatoes in containers can prevent a lot of pest and disease problems. Avoid planting tomatoes too early when they can be killed by a late spring freeze or struggle to absorb nutrients from cold soil. Potassium can wash away more easily in soils that are light, sandy, or chalky, while heavier clay soils hold potassium naturally. 2
