Of course it can be saved.
I see enough energy leafs there.
Clean her up a little. Cut those leafs, not all just the crisp, or not, it's not nes, but if you want to make sure you are out of nutrient burn you'll need to cut back to green to notice any on going probs, now normally I'd say look to new growth, as I burnt the shit out of 1 of my gorilla zkittlez but I have enough new growth to know its been out of danger weeks now but just looks bad but in reality she's very healthy.
I see a lot of healthy growth left, (even those burnt leafs, look fine)
Good luck pal.
