The second pic looks perfectly healthy to me. :)

In fact, the plant in general looks okay. Are all of the spots on the lower leaves, or are there some higher up?

My thought is that transplants make a certain adjustment when going to low light (indoors) to lots of light (outdoors). The leaves made while it was indoors have less chlorophyll, but it's set at that level when the leaves emerge -- it can't just "green them up" a little more. So as it makes new leaves which are adjusted to the high light level, it retires the old ones. They get yellow, curl a little, and sometimes get some brown spots as they die off.

I've had transplants which are skinny sticks with a tuft of a couple of leaves at the top, because all the others got yellow and fell off as they hardened off. Yours looks better than that. :) If there are spots in the upper leaves, then you may want to consider taking some action, but if it's all down low as it looks like, don't worry about it.
