No that's all you need for a potent mix. I use mycogrow soluable aswell but that's just because it's so cheap i save some cash using less of the zho and aquashield. But it's redundant as all the microbes in it are in zho/AS aswell. So your mix will be fine.
What ive learned brewing; dont put a tonne of ingredients, it'll strip the water of disolved o2 quicker than it's replaced, LOTS of air, dont add too much molasses. (I use brown sugar disolved in warm water) because if it's not eaten up when you add your tea(at 48 hrs) it'll feed the bad microbes and make things worse.
Good luck keep me posted
