In my case, I cant see anything suspicious.
No insects and no fungus on the leaf.

can be due to overwatering or underwatering, in your case as it is not in the pot so most likely it is due to underwatering.

Hello! What is the situation now?

Hello! From the picture you attached, it looks like your Alocasia plant might be experiencing some leaf discoloration and browning. There are a few potential causes for this:

1. Overwatering: Even if you are checking for soil moisture before watering, it's possible that the plant is getting too much water. Alocasia plants prefer moist but well-draining soil. If the soil is staying too wet, it can lead to root rot and cause the leaves to turn yellow and brown.
2. Underwatering: On the other hand, if the plant is not getting enough water, it can also lead to leaf discoloration and browning. Make sure that the soil is not drying out completely between waterings.
3. Nutrient deficiency: Alocasia plants require regular fertilization to maintain healthy growth. If the plant is not getting enough nutrients, it can cause the leaves to turn yellow and brown.
4. Environmental stress: Alocasia plants prefer warm and humid conditions. If the plant is exposed to cold temperatures or dry air, it can cause the leaves to turn yellow and brown.
5. Pest infestation: Although you have checked for pests with a microscope, it's still possible that the plant is being attacked by pests that are too small to see, such as spider mites or thrips.

To address the issue, try adjusting your watering schedule to make sure the soil is moist but well-draining. You may also want to consider fertilizing the plant with a balanced fertilizer. Make sure the plant is not exposed to cold temperatures or dry air, and keep an eye out for any signs of pest infestation. If the issue persists, it may be helpful to consult with a local plant expert or horticulturist.
