I was afraid of having to actually ask about something

[discrepancy]

So, naturally, Murphy's Law strikes.

Just noticed these leaves today on my Gold Medal plant. One reminds me of Septoria leaf spot, but no fruiting bodies are present, and I'm definitely not sure about the black spots. There's nothing on the stem, either. The only thing I've done to the plant since sticking it in the ground was give it a fish emulsion fertilizer applied directly to the soil today.

Can it be attributed to general crankiness over being overwatered (transplanted right before a solid three days of nonstop torrential downpours), or is this something serious?

Sorry for the trouble. Any help would be appreciated. eek!
