got some avocados there alsBo any help is welcome

I would say the tree in the first photo is deficient in magnesium. Magnesium deficiency can be corrected by dissolving 1 tablespoon of Epsom salts in a gallon of hot water, then applying the cooled solution to the root zone. Repeat this treatment every week until the deficiency is corrected. NOTE: Epsom salts does not dissolve cold water, therefore be sure to dissolve in hot water.

The last photo is showing a manganese deficiency, because of the green borders along the veins.- Millet (1,150-)

I just applied a 12 5 8 vigoro fertilizer with 1.00 magnesium you think that is sufficient to correct my issues
and any idea on middle pic?

An additional note; The last picture could possible be an iron deficiency. Iron deficiency, and a manganese deficiency both appear on the NEW leaves, and both deficiencies have green veins with otherwise yellow leaves. The difference is, with an iron deficiency there is no green border along the veins, a manganese deficiency looks similar to an iron deficiency except in a manganese deficiency there IS a green border along the veins.

My guess is that a one time application of a granular fertilizer containing a 1 percent magnesium will not be enough magnesium to resolve the situation.

I have no idea about the middle picture.

One thing could be the cause of your problem.It seems to me that your lawn is too strong and too near from the trunk of your citrus.
It makes competition for the food. You better clear one foot more around your citrus.

A high pH can make it difficult for the tree to take in the minerals it needs--you should check pH--citrus prefer pH of about 6 to 6.5

I just cleared two feet around all my trees and compost and mulch were applied. My ph levl is 5.8-6.2.
I will be appling Epsom tommorrow on my avocado. My citrus don't hAve the green veins so my fertilizer should be sufficient for the iron?

Don't let the compost nor mulch touch the tree's trunk. - Millet (1,149-)

Thx millet will be following up tom on Epsom salt
and yeah I dug up the old dirt and placed around trunk then I composted and mulched maybe six inches away from trunk
