Severe nute burn should I harvest at 3 weeks into flowering? pics included

First of all let me say this is EnjoyIt's wife so I really need help AS I'M NOT THE ONE WHO USUALLY CARES FOR THESE PLANTS. And forgive me if this post is on here twice wrote this all before attached pics then accidentally hit back on my browser. So he has a previous post on this called "Will this turn to bud rot?" The plant has some serious nute burn and is getting worse. It's in a 5 gallon container and he flushed it with 8 gallons of water. The soil is still wet according to his moisture meter from the flushing Sunday. He's using FF organic soil and Humboldt organic nutrients every 4 days until this nute burn happened. Some of the buds (colas whatever you want to call them) are turniView attachment 1109196ng brown at 3 weeks into flowering should I cut and trim these now or stop wasting my time with this plant and harvest thView attachment 1109195e whole thing?

So I feel pretty screwed in this situation

Wow man, sorry to see that. There is not much left to do for this plant. If all of its problems are sorted out it may still continue growing, but with the small amount of healthy leaves left it may just be a goner.

That thing is really burned, might be lost.

Do yourself a favor and take a step back then bitch slap whoever did that to your girl.

Re-plant it in plain old NO NUTES soil and water it good. I had one that I fried like that. It took a few weeks but it bounced back.
Depending on the strain, it may or may not be worth the time. You might get lucky giving it fresh zero nute soil, water, and some TLC.
Your going to need to be on the ball about PH levels. It's already hurt and off PH will not help it.

pretty much every leaf is burned on it...if it dont start producing new growth after a good flush...then i would just harvest what bud is there.the buds will stop developing and start losing what little potency they have.the buds need the leaves as much as the plant itself does.id give it a couple more days to let the shock wear off...if no new leaf growth happens...chop it and start over.
