I think this one is Echinocereus fererrianus but the books say flowers should be deep rose pink.
These blooms are very light pink,almost white. Any thoughts on this one?
It's in a 3 inch pot. Thank you.

Could be as it is variable in spination. The typical form has yellow flowers (aurea = gold) but evidently has red flowered forms too as well as other colours.
The "Lobivia" section of Echinopsis is endlessly messy. So many of the species vary phenotypically in significant ways and it can be difficult to know exactly what you have because of that but also because of their descriptions.
It happens often enough that in any given scientific description, the first population found and studied were not particularly representative of the species as a whole, or that those which were initially taken into cultivation are not particularly representative. Plus, hybrids do occur naturally and ring species are formed.
Then add the complication that any given plant may have a million pictures on Google showing the same thing, but they are all the wrong species.
Given all of that, sometimes there are plants that you know are Echinopsis (or the Lobivia subgenera therein) but that's really as far as you will get an identification. The exact species may elude you.
This has happened with me, where seeds from the same plant have produced really different looking seedlings. At a certain point the classification process will make you crazy if you let it. lol
Do you think possibly Lobivia aurea? I've read the blooms can be yellow,pink or white.
