CAN THIS BE FIXED IF SO HOW WOULD IT BE DONE

ADVICE NEEDED
damn dude what'd you do? it looks like major nute burn to be honest it doesn't look like it can be saved but anything is possible i wish you the best of luck but man that sucks
the most common mistakes are over watering and over feeding
i would get new soil (organic is better, no chemicals and it seems to be a bit easier) and it'll be easier during harvest
so get new soil, water right after transplant (do transplant during dry soil) i also suggest to study up on some soils this site is already a great spot to research cause theres so many questions and helpful people on here
but good luck with it and i hope you don't have to restart
