That is certainly correct. And once you get more familiar with the micromanagement, you'll (hopefully) learn to love it, or at least understand how important and powerful it can be.
Kind of in that vain, I think it was a mistake to settle the NW gold where you did. 1N, where it was originally intended, is better, because you get the corn in inner ring, and can thus work corn + gold very early on, and still grow. You couldn't even improve the cow for a good while, so I don't know why you founded it there. Marble can be claimed later. It isn't important that early. It becomes more important when you unlock Aesthetics and Literature.
Soon you'll get Civil Service, which is very strong with a well-cottaged capital. It also means you can chain irrigate. If you're not familiar with that, it means you can put several farms next to each other, from a water source (river, lake, oasis), and towards an un-irrigated corn/wheat/rice plot. That gives you +1

on that plot, because it becomes irrigated. The wheat next to the river SE is already irrigated btw, but by using chain irrigation you can irrigate the corn further NW. Unfortunately you need to expand borders first, because corn wasn't in first ring

(Or has that happened now?)
Cites that aren't located on hills also chain irrigate btw, so the city you're about to found in the east will automatically irrigate the corn there (from the lake), once you get Civil Service.
