Hello and welcome. 
I am far from an expert, so hopefully some will chime in.
That said, my understanding is young trees should be given a good 8-3-9 with minors.
Once established, 0-0-50 (no nitrogen) is used to assist with fruiting.
There are other specialized fertilizers/amendments which can be used, if/when a tree shows deficiencies/signs of needing them.

There is plenty to read on this subject in previous posts, with a little research you can find answers to questions you never knew you had.

what you mean by "with minors"  ?
i still would like to know if nutrients can be given in solid form other than foliar spray to mango tree?

my mature mango tree is having leafs burns and i think its lacking something.

A little googling or searching the forum should tell you all you need.

If you think your tree has an issue, there’s a specific topic on which you could post pictures and ask for help.
