Boy that's gonna stink! LOL.

I sometimes use liquid fish emulsion. Remember this is high in nitrogen, so you want to be careful with it. Nitrogen helps plants grow their green parts, but they'll favor greenery over blooms and fruits with too much nitrogen. Depends on what you're feeding.

The corn meal is also nitrogen, but is good if you have any fungal problems. If not, I think mid summer I'd skip it. The sea weed I'd definitely add. I love seaweed and think it has a lot of good properties. (I buy the liquid stuff)

Molasses is good, too, because it feeds microbes. I'm not sure what the vinegar does other than fungal control.

If it were me, I'd go with adding the seaweed and molasses and skip the rest. What plants are you planning on feeding?

p.s. That's just me, and I'm not an expert on this...I just know what I do and what has worked well for me.
