Mango seedling leaf diseases.

Mango    None Given

Hello so I am growing a mango plant indoors the plant is 3 months old, but the last 1 month is a hell for me since the plant is suffering from few leaf diseases. If you could help me to identify the problem, it would be very grateful. Here are the pictures of the diseases.

I think you may be dealing with Anthracnose, a fungal disease. Read up on the symptoms on this page (scroll down to that disease):

Thanks for answering Gabriele. We also have anthraconse on our Mango page https://www.plantvillage.org/en/topic... but since this plant is in doors I am wondering if maybe it might be a physiological stress as Ravi suggested.

How frequently you water the plant? I suspect it could be a physiological disorder called Oedema. Oedema occurs due to excess water retention in the tissues. The main symptoms are appearance of small raised areas on the lower surface of leaves. This pinhead swellings appear water soaked initially and later turn brownish or black color patches.
This disorder is caused by excess watering and high humid condition.

I water the plant when I noticed that 2-3 cm of the top soil is dry, but my soil had a large amount of perlite so I am watering every 7 days, I think this may the problem. For anthracnose (fungal disease) I tried with baking powder and neem oil soap, but no difference in disease.

Dr. Ravishankar Narayana commented,
Yes, more perlite in the soil may be the problem. Normally perlite aid in water retention. Due to its large surface area, perlite is advisable for the plants that prefer high humidity, since the evaporation of water from its surface area creates higher humidity levels. https://www.gardeningknowhow.com/gard...

I agree with Ravi, this is probably oedema due to the patterning of bumps on the underside. Have you tried the perlite yet? https://content.ces.ncsu.edu/extensio...
