Planting sweet orange seeds do  not grow sour orange trees.  Most all sweet orange varieties grow true from seed.

 In the case of citrus, not all but most citrus seeds do grow true to their parent.

 True from seed:  Almost all sweet oranges, true grapefruit, lemons, pure mandarins (other than King & clementine), most tangelos, hybrid tangerines and Tangors (except Temple).  Most pummelo do not grow true from seed.

Yes, but if the apical bud is not removed the tree will grow higher and spindly.  Most all commercial nurseries cut their trees to 2.5 ft.  I seen a picture of a seedling citrus tree on another forum, that was about 6 or 7 feet tall with no  side branching at all.  That picture shows the power of apical dominance.  The tree was held up by a long stick.

Your tree is showing a strong apical bud dominance.   The apical bud is where new plant growth and elongation occur. But that’s not all the apical bud does. The apical bud produces a plant hormone, auxin, that flows through the plant’s vascular system (phloem) down the stem, and inhibits the elongation of axillary buds which would otherwise produce new side shoots from the plant cells.
  I would cut off the top 25 percent of the top of the  tree, which will cause your tree to produce side ranching.

Find a fertilize that contains all three major ingredients N, P and K plus race elements. 

Yes, But for soil application through the roots you would be better off using a ammonium nitrate formula.

There is a common situation called June Drop.  June Drop occurs both in the months of June and July.  Most all trees suffer from it.   My inground Cara Cara experienced June Drop last week, dropping some golf ball sized fruit.  You can find a lot about June Drop  with a computer search.

I don't think your trees symptoms come from the LED lighting.  The leaves are showing the typical sign of an iron deficiency. The leaf symptoms for iron deficiency are:  New leaves with green veins on otherwise yellowish leaves. An iron deficiency is often caused by high pH rather than a shortage of minerals.

For a tree without fruit, the urea spray  would just be a general nitrogen source.

Was the fruit load heaver last year than this year?

I have not grown Early Saint Ann, but i have grown Xie Shan for7 or 8 years in zone 5 greenhouse, and it is ready in September.  I would also add, that at several of the Southeast Citrus Expo citrus best taste testing contests that I attended Xie Shan was the winning variety both times.

If you want to actually grow a good (excellent) tasting early maturing citrus, then grow Xie Shan.  It is ready to harvest in September.

Like Jakefruit intimated, one of the very first things a person thinks of when a newly summer planted tree in Phoenix is having problems, is the watering schedule.  In  the Phoenix area I would plant a new citrus tree in the fall months.

I used to have a large in ground Bizzarria orange tree (6-ft.tall and 8-ft wide) It produced a lot of fruit, but the only thing one can do with the fruit is look at them.  I finally chopped the tree out and replaced it with a Red Grapefruit.

Citrus General Discussion / HLB Spreads In California
« on: July 08, 2022, 12:55:08 PM »
USDA APHIS added portions of Los Angeles, Orange, Riverside and San Bernardino counties to the quarantined areas. With the expansion of the Jurupa Valley and Riverside areas of Riverside and San Bernardino counties in the HLB quarantine area, CDFA merged the HLB quarantine boundaries, creating a single HLB quarantine. That quarantine expands across Los Angeles, Orange, Riverside and San Bernardino counties. In addition, APHIS is establishing a quarantine in a portion of San Diego County. APHIS is taking this action because of HLB detections in plant tissue samples collected from multiple locations during routine surveys in California.

Have you ever pulled the tree from the container and examined the roots?

Every container has a layer of perched water, even containers without an actual bottom.  Roots will not grow in the perched water portion of the container.

Covering the entire root ball with the medium, has nothing to do with the purchased water table.  Looking at the picture again, it certainly looks like the container is not completely filled. 

Why is the container only 1/2 full of medium?  The perched water table must occupy most all of the tree's root zone area, educing much of the root's oxygen. 

My guess all  the trees that cannot stand on their own roots were transplants, that were not planted properly,  For now stake them up.

I noticed you listed Ponkan Mandarin on the don't want list.  Ponkan is not only a good fruit, it is a great tree..  I would urge you to reconsider.  You will be happy if you do.  Thanks for sharing.

The 1,000th tree okayed for growing by California’s Citrus Clonal Protection Program happens to be California's oldest orange variety in the state. Dubbed the Mother Orange Tree, Bidwell’s Bar is a sweet Mediterranean orange brought to California from Mazatlán, Mexico, and planted in 1856. It was first planted near the Bidwell Bar Bridge near Oroville.

The tree’s survival skills are some of the reasons Tom Delfino, former California Citrus Nursery Society director, recommended it for the protection program. “Apparently this variety is very rugged,” Delfino said. “Not only has it survived a lot of cold Northern California winters, but the tree has been dug up and replanted twice — once to protect it from impending flood, and again to make way for the Oroville Dam.”
By suggesting Bidwell’s Bar for approval, Delfino was hoping the protection program would clear it so he could buy its budwood. On the occasions he has visited the original tree, Delfino said the fruit in reaching distance was always gone. “I think it must be tasty because locals grab it for themselves,” he said. “Makes me even more eager to grow and eat my own.”
Delfino also hopes that this variety will catch on with commercial growers. “My thought is our citrus industry is concentrated in the southeastern San Joaquin Valley and is subject to a number of pests that like the warm climate there,” Delfino said. “Though this has seeds, which may be a deterrent, it can be grown in colder areas that discourage some of those insects.”
California’s oldest orange tree arrived in California nearly two decades before the better-known Washington Navel orange grown by Eliza Tibbets in Riverside. “Bidwell’s Bar is an example of what was grown in California before the Washington Navel came to dominate,” said Tracy Kahn, curator of the Givaudan Citrus Variety Collection at University of California, Riverside (UCR).
Kahn says it’s important to preserve the genetic material from a tree with such significance to California. “Some people were worried it was going to die, but now we have an officially cleared source of this historic tree, and it is protected for future generations,” Kahn said.
The Citrus Clonal Protection Program, housed at UC Riverside, is the first of its kind in the world. It began in the 1950s, and its scientists spend up to three years testing and clearing citrus trees of disease so they can be released to commercial and private growers. By law, every citrus tree newly propagated in California can be traced back to one mother tree created at UCR through the protection program.
