i almost killed my plant

2 hours ago i fed it double the nutes it needs, on accident, wrong jug and what not, now i checked on it and it is alll curling up and leaves ar turning crispy and black, should i take cuttings to maybe make some clones, cuttings of the ones in good shape?

oh btw, i am already flushing it and everything

just flush it out till the water runs clear be fine cannabis is hard as fuck plant take a lot to kill them

If you are gonna take some cuttings I would do it soon incase the issues spread to the whole of the plant. A good solid flush though and you should be good to go.
