Grey Leaf Spot?

[Gussie]

Based on my Googling, I am pretty sure I am dealing with Grey Leaf Spot on my Caspian Pink.

Quick Stats: Purchased plant at a local greenhouse. Planted out approx 2.5 weeks ago in Promix (I think this last batch I got was not BX). Earthbox with the auto water system. Espoma Garden Lime and Tomato Tone per EB directions. Planted next to Omar's Lebonese, which shows no signs of illness. Oh, and in case I didn't do something right in my profile, I am in Northern Virginia - Zone 7.

I have attached photos in the hopes (fear?) that you guys can confirm. I just did a foliar spray of Actinovate so I can stop stressing and go to work, but not sure what else I can/should do. Happy to hear any/all advice from you experts who have enabled my rekindled love of tomato growing.

Trying my darndest to stay organic, and my 14 other plants are loving life. Well, except for the Cherokee Purple that I accidentally over de-suckered one day. Poor guy is still trying to figure out how to grow now that I stopped pinching him.

Thanks!
