Week 10 of flower, Fan leaf tips burnt

Ok, so I overdid it with the recipe for success in that at week 10 of flower all my fan leaves have about a mm of burn right at the tip.

My question is the following:

Can this be rectified by a good flushing over the last two weeks, or no matter what should I expect a harsh smoke/vape experience?

Crank back the nutrient concentration a bit. The leaf burn is just the plant sacrificing leaves to save its health.

The plant is perfectly fine, the leaf tips are the only thing screwed. Give it water for a day then go back to a weaker nutrient solution.

Flush the last week if you really want to flush that badly, 2 weeks will destroy your bud output.
