Tomatoes are a fragile crop.
Quite often, beginners and even experienced gardeners are faced with the fact that the leaves of plants turn yellow.
The condition of the leaves is an indicator of plant health.
This may indicate problems with care or signal a deficiency of an important element. In the latter case, you need to carefully examine the leaves. If they turn yellow evenly, this indicates a lack of nitrogen.
If the veins are still green, then there is an iron deficiency.
If they turn yellow and dry out at the edges, this is a sign that potassium is needed.
Light yellow spots indicate that tomatoes need manganese.
In such cases, it is necessary to apply fertilizer to correct the problem.
If we talk about mistakes in care, the leaves can start to turn yellow if the watering regime has been violated, the plants are too cold or too hot, and there are also problems with lighting.
