Q.Mango tree from seed
I live in Egypt where the weather is currently winter with highs of around 17 degrees and lows of 7 or 10. I have planted a mango tree from seed about 3 months ago. It has been growing very well in my balcony where there is a lot of sun. Lately, however, the leaves have started developing bronze like color at the tip edges of the leaf that works its way inward to occupy the whole leaf. I am wondering is this a disease or is it just a natural wilting because of the winter?
Thanks a lot.

We did not receive the image of your tree.
It could be sun scald on the leaves or even a fungus.
Make sure the leaves are not splashed with water while watering the tree.

Neem Oil can be used to treat the leaves if the problem persists.
