Citrus trees have yellow in the leaves (forum)

No pics, comma. There are many many threads on this forum that deal with "yellow leaves on citrus" and as many reasons for them. Put those words in the box that is on the top right hand corner of the page and click Search the Forum and you will find them. Those threads would have appeared below your question when you put in your subject line. Usually reading through those would help you find the answers without having to start a new thread.

I am very new to citrus. I just purchased a Key Lime, Lemon, and Kumquat tree. All are fairly old and starting to show fruit. They are potted in 7 gallon pots and that is where they will stay (I am not planting them in the ground).

I water them every other day unless it is very hot and then every day. I added a citrus plant food when I bought them. They are in a mix of porous potting soil for fruit/veggies and a citrus specific potting soil.

I have noticed they all have yellowing of the leaves. Only in certain areas of the tree. Other areas are perfectly green. The lemon tree had this when I bought it, the others have developed it over the past week.

Any idea what this could be and what I should do?
Pics attached.

Pics added. They must not have updated before.
The threads I could find about this all the replies said it was basically a case by case basis and pics of the specific leaves were important.

Pic 3 too dark to make out. Pic 2 may possibly have an early zinc deficiency.
All citrus has what is called 'winter yellows' which naturally improves as the soil warms up in spring.

I would wait till the weather warms up to see how they go. They won't die in the meantime, they look basically healthy.
