Smokesteve , I can't see your whole plant, but that does look like zinc.
But if your in good soil, you shouldn't have to worry about zinc, it's in there.
If she was mine ,I'd topdress a couple of inches, of that soil you got, and water it in real slow, maybe even mist it in.And see what she looks like in a day or two.
If not that, I'd mix up some Recharge
an charge all those microbes and bacteria back up, that's in your soil.
But I'd be using more molasses than you probably.
Teas are awesome ,they help alot.
GoodLuck,
