I have two different species of mango trees, both about 4 years old. even though its a little early they both produced mangos this year. but now after the tree has been growing at an amazing pace the top of all the branches with the new leaves are drooping down as if it is too heavy to support its own weight. i suspected over watering but really i don't know, i am using a 20-20-20 fertilizer if that helps. please if anyone knows or has any ideas as to what is happening, my tree would really appreciate it.
