Your root system is probably damaged too. Now You need to be really carefull.
Keep Your soil moist, but not wet. Your's is too wet (saying by looking at the latest pics)
*Really* small amounts of nutes can be given, weekly, but not with each watering.
But first of all , You need to concentrate on the roots.
If I were You, I'd also add a really light mix of perlite and potting soil mix on top of the pot.
Or better, I'd transplant it to a bigger pot.
You still have a chance to make something out of this. But it it wont be a perfect yield.
Still.. This is life.. And anything can happen
