I hope not that is what I was thinking I pulled All the leaves off of look like that and they haven't came back yet. Now it's got some other deficiencies like a light green and some purple color you know what that is. You can tell the color difference from the plant in the back and the purple ish leaves on top.
A telltale sign of spots being septoria is you'll see a yellow ring around the spot where the tissue is going necrotic. You did good to remove infected leaves. Get the humidity down and make sure you've got good air circulation. Try not to let any moisture sit on the leaves.
Edit: I saw a Pic of this plant in another thread. Multiple deficiencies noted in the mid section, you probably have a salt pocket hiding in the root zone.
