Causes yellow color of leaves in tomato seedlings

Most often, the leaves turn yellow if the plant is not enough nitrogen in the soil. Therefore, the need to feed the nitrogen fertilizer (ammonium nitrate). Consumption of the solution - 1 tbsp. spoon on a bucket of water. It is possible to use ammonia (ammonia), spreading it with water (2 tbsp. spoon on the bucket).

But if the plants are warm, but there was a purple color, what is the reason? It's simple. So it's not enough phosphorus in the soil. What's in this case? It is necessary to feed the ash solution (except for potassium, and phosphorus is there) or fishmeal, any phosphorus-containing fertilizer (1 tbsp. Spoon superphosphate per 10 liters of water).
