Mold or something else?

[gimmieToms]

So this was the tomato plant that I found with mold on my new bamboo pole. I cleaned the pole only with a high bleach water mix and a toothbrush. A couple days after I noticed splotches on the leaves that were dark green and dry. I put this down to probably dropping bleach water on them while cleaning the pole. This is now 3 consecutive days and I noticed a dark patch on the stem, that I cut off. To be safe, I treated all my tomatoes with bordo copper spray this morning.Then I see this. Not sure if it just developed or I missed it this morning, but I cut it off anyway.
When I had mold last year it was dark grey, this is brown.
What do you think this is?
