Help, Fert Burn recovery

[Bleezy]

So the other day my plant was suffering from a fert burn, i flushed the plant and she got a little rain too, the plant is looking strong again but the leaves that were turned brown got it pretty bad i was just wondering if they will ever go green again? or is there any way they will fall off or i can snip them off, the plant is about 3 weeks old.

any input is appreciated thanks.

There should be almost no need to fertilize at 3 weeks old.
