According to research citrus absorb nutrients in a 5-1-3 ratio. Meaning for every 5 parts nitrogen the tree absorbs it will absorb 1 part phosphorous and 3 parts potassium, plus trace minerals.    The 10-10-10 fertilizer you used has a 1-1-1 ratio.   Try to find a fertilizer that has  higher levels of nitrogen and potassium and low levels of phosphorous.  Be sure it also has trace minerals.  A half cup of 10-10-10 per a 15 gallon container is a lot of fertilizer.

Going from a 4" container to a 15 gallon pot is normally a real killer.   From a 4" container into a 1-gallon container, then into a 3- gallon container and into a 5-gallon container and on and on is best. 

Looks under fertilized to me, the leaves has the symptoms showing a nitrogen deficiency.  What fertilizer do you use, and what if you fertilizer regimen?

The Dekopons on my tree look ready, but I'm waiting until February before picking.  I've read that leaving them on until February they develop more sugars.  I have eaten some from time to time, and as they age on the tree they have become better.

Beautiful tree.  That is a very healthy tree.

Lime leaves are more rounded at the tip, whereas Meyer lemon leaves are more pointed.

It is a simple matter to determine if it is some type of a lime.  Cut the fruit in half and examine the pulp.  If the pulp has a greenish tint to it and the aroma is typical to a lime then your tree is some type of a lime. If the fruit is also seedless and large/round then it is probably a Bearrs Lime. If not then I agree with Meyer Lemon.

Laaz, believe me, my son and I found that out, it burned the mouth for 30 minutes. .  Now two days later, some pepper's residue is still on my hands, even after washing them and doing the evening dishes.  They are certainly HOT.   I planted the seeds.

It took over a month for the mandatory spraying to begin.  A psyllid could do a LOT of damage in a months time.

Any citrus tree, including lemons, will grow to be dwarf in size just by growing in a container.  You can also graft, or buy, many varieties of citrus that are grafted on dwarfing rootstocks from Four Winds Growers, which can be found on the Internet.  Their trees are generally high quality.  Lemons flower and fruit all year around, however their main crop is during the summer months. Citrus varieties can be easily found on either dwarfing rootstock or standard rootstocks which produce full size trees.  I grow many of my trees in the ground on dwarfing rootstocks inside my greenhouse.  Mr Cara Cara Navel orange was grafted upon Flying Dragon (dwarfing rootstock) is now 11-ft. tall and wide and is 12 years old.  Meyer Lemon is a very vigorous tree, and a larger tree should easily produce 100+ lemons.  To spread the lemon use year around, you can juice the fruit you can't use right a way, and freeze the juice in ice cube trays.  Mandarins, depending on the variety, fruit from September to March. Grapefruit require a lot of heat to produce high quality

There’s a new mandarin orange in town: the Super Nova. For almost 50 years, the fruit has tantalized visitors to university citrus variety collections with its gorgeous dark orange color, its convenient seedlessness, its rich balance of sweetness and acidity — and its superb aromatics. Now, this mandarin is finally available commercially. And although the citrus won’t chase Cuties and Halos from markets any time soon, its excellence is outmatched only by the curious convolutions of its history and nomenclature.

It was in 1966 that Jack Hearn, an Orlando-based citrus breeder for the U.S. Department of Agriculture, crossed two sibling mandarin varieties, Lee and Nova, seeking to understand their pollination requirements. By chance, one such hybrid, then called 6-13-44, had extraordinarily fine flavor and was seedless, a rare trait among mandarins at the time. It had only one problem: The trees bore no fruit.

“In 34 years, I’ve seen it yield a good crop exactly once,” said Randall Driggers, a USDA researcher based in Fort Pierce, Fla.

Hoping the variety might produce better in California, Hearn in 1988 sent budwood for propagating to UC Riverside, where it  became known as USDA 88-2, Lee × Nova (thanks to its parentage) and Novalee. There, indeed, the trees did bear moderately successful crops, though not exactly gangbusters.
