Too close to harvest to bother?

I was thinking light burn...but I'm using LED and it the only one showing these symptoms. Temps are 80ish with 60% humidity . They are 48 days from switching to flower. Do I even bother at this point to try and correct it? It's a soil grow and I only use water. I've got another with what look like a nitrogen deficiency but it's not too bad. The strains say 60 days to finish but I'm counting from the switch to 12/12 so I may be off a bit on my timing.

,I think you over nuted and have potassium lockout

I had a problem that I thought was potassium,but it turned out to be led light burn.It only got bad after I switched to perlite hempy buckets,I tried everything to fix it.I accidentally read an article about light burn,it was describing my trouble to a t.Adding dimmers and raising the lights solved the problem.It was strange that it affected the older fans first and never really bothered the bud leaves.

Beautiful plant.

let her finish.
I'd add some composted chicken shit yesterday though.
