Apply thin fertilizer frequently, adjust the concentration according to the seedling situation, the concentration of small seedlings is thin, and the concentration of big seedlings is relatively higher. The growth of strong seedlings is strong, and the concentration of fertilizer can be thicker than that of weak seedlings. After fertilization, pay attention to observe the state of the seedlings. If the leaves become soft the next day, the concentration is too high. You should immediately drench the roots with water and dilute the concentration.
