Thanks for that. They are growing in direct sunlight for the most part. I water them every day. They are growing in small pots (4inch diameter) outdoors in potting mix. I tried feeding them some dynamic lifter to no avail. Diagnoses now for large splotches are sun-damage, inadequate water or fungal infection? Looking at the small little round black spots. There seems to be two categories: 1) Dry and can be brushed off. 2) Wet, and can be spread. Diagnosis for black spots now are insect related?

It looks like it was really fried on that hot day.I'd take it out of the full sun for awhile,not complete shade,kind of dappled light if possible and gradually give more light. What's the potting mix? Brady

"I bare rooted and potted up. I gently teased the roots, and removed all of the soil. There was even a worm in the dirt. Only a few roots were lost." Why you did this? Did the seller ask to do? I had bought more than 15 mangoes from FL to CA in the past and never do this, and none died during repotting. I think the major issues are root shock and not enough water in the media. You need to place the whole pot into a water bucket for 10 minutes, then take out and place the pot in a warm out of sun spot, cover the tree with clear plastic bag to keep the leaves moist. Sapote

That's an awfully big pot to start that little guy in. Overwatering sounds about right-a heavy soil like that, along with being in a pot too big for the plant.. transplant into a smaller container, doing your best not to disturb the roots. That's just my thoughts on it-I'm sure some more seasoned posters will provide additional input.
