All anyone can do without seeing the plant in person is make suggestions.

I can tell you that a very common reason for the failure of container grown plants is problems with the choice of a potting medium. Second on the list would be improper watering.

You should be aware of how moist or dry the soil volume is by digging a bit with your fingers. If dryish to the touch, you should water (drench) thoroughly.

do not send me your pix... figure out how to post them ...

did you protected the transplant from direct sun for a few day.. a week.. a month ????

or blast it out into full sun???

it is not uncommon.. when planting or repotting.. a fully leafed out tree.. to lose some leaves .. its called transplant shock ...

how many you lost is the issue ... and what the buds or growth tips look like ...

in a sense.. the tree sacrifices older leaves... to maintain the growth points ...

and w/o that pic.. i cant give you any more ...

ken

here are some pics of what im having trouble with. it is not on all leaves. on both new growth and larger leaves. most r still looking good i just dont know if i should worry

Environmental stress.

At 100F, rig temporary shade or move it into the shade.

Just a thought...what are you watering it with, unfiltered city water? If your refrigerator has a water dispenser use that at room temp. San Diego city water is awful for plants. ;)
