JakeFruit,
Spot spray with hydrogen peroxide till ooze dissolves, wip off with papertowel, spray again.  While still freshly open, spray whole tree and wounds with any Copper Sulfate Pentahydrate product.  If you only have Copper Octanoate or Ammoniated Copper, those will also work.

Jagmanjoe,
Wind damage followed by fungus infections: Anthracnose, and probably also Cylindrocladium.

3rd picture:  mineral deficiencies--- Zinc, and probably Copper and Sulfur.

Thank you very much for taking the time to provide your valuable input, Har

Spray it several times with Copper products.  Then the tree's bark will probably heal over that spot.

Do I have to clean some necrotic tissues under the bark?
I sprayed copper product a week ago. Now it doesn't look better even worth after rain.
Does this product will be able to help? After spraying copper?
Thanks a lot

Healing will take over one year.

I don't know that product.

Don't know what are the dark patches on both the old and new leaves of this new mango tree. Someone can help me on this.

Dead tissue, from previous infections or spray burns.

Many of my mango seedlings have twisted (in some cases looped) trunks right around the soil line (see photo). When planting should these planted below soil line, currently putting them in the ground and just planting them level with where the soil line was in the pots I received them in

Tonyma,
Perhaps a burn from spray in very hot sun, or from pee, from a pet or tree frog....

Honey Kiss, planted last summer from 7 gal pot. Seems to be doing well.  But I noticed this the other day on a few leaves.  Any idea what might be happening?

Looks as though a large insect or snail scraped the surface of the leaf.

Interesting.  I'll have to keep my eye on this.  Thanks, Guanabanus.

Upon further review, whatever this is has spread to several leaves.  In the photos you will notice white spots on the tree.  The house painter rinsed off some brushes nearby and got some on the tree.  I don't think this has anything to do with the browning on the leaves.

What is causing these depressions on so many of my fruit this year? The depressions donít penetrate the deep layer of skin. The black spots are not eggs.

What percentage of your fruit has this problem?

Probably a mineral imbalance, such as a Boron deficiency.

My atulfo rootstock trunk has large crevices/splitting. It was originally 3 plants that popped up by I cut one of the trunks off. Haven't decided if I will cut the other trunk off yet. Trees are about 8 ft tall with Sweet tart grafts that appear healthy. Is this normal or a problem?

Normal bark aging, probably.

Tell me what I should do with this mango tree

Hi, this Glen mango has been in the ground for one year and has really grown well at the top. However as you can see the trunk is not keeping up and it pretty limber considering the mass of foliage, and requires a tripod of stakes to protect it from wind. I bought the tree in this general shape but much smaller and thinner at that time. The trunk diameter has doubled (to 1.5") however the top has more than quadrupled.

The top is 5 feet wide, the trunk is 4 1/2 feet tall from ground to foliage and is 1-1/2 inches thick. I am afraid that at some point in time the trunk will not be able to sustain the top foliage, so I am asking if there is a specific formula of fertilizer that will focus on growing and strengthening the trunk; or do I need to severely cut back the top to the primary nodes on each  branch; or is this tree a lost cause?

Appreciate the help!
