Should I add more vermicompost for yellow leaves?

Only if watering/light are correct and growth is active. Otherwise you risk organic overload on damaged roots.

Yellow leaves, causes and what to do first

Ready to stock your garden?

Soggy pots: yellow + drop + possible smell-reduce water, improve airflow.

Bone dry long-term: yellow crisp edge-rehydrate slowly.

True deficiency is rarer in fresh potting mixes-rule out water and light for weeks first.
