The situation can be aggravated by the fact that the yellowed leaves begin to fall off. And in order to correctly determine the cause of the problem, it is recommended to carefully examine the culture. The reasons for which the leaves become yellow can be very different.

Often gardeners growing seedlings are faced with the fact that it turns yellow. This is due to the fact that the young sprout needs a large number of macronutrients and nutrients.
Wrong care for seedlings

- lack of ventilation;
- burns from the sun or lighting fixtures;
