Lockout is winning in flower, any strategies to salvage and limp to harvest?

1st grow, of course

I have been fighting what I believe is a phosphorus deficiency/lockout for like 2 months now but it has escalated in the last few weeks. 5 of the 8 plants show some level of this. I have been pulling my hair out trying to figure it out but at this point I need to focus on salvage. If you have input on the lockout please see this thread. https://www.rollitup.org/t/having-trouble-with-a-diagnosis-ideas.959599/ I am still going to try to minimize the problem but my understanding is that they wouldn't recover at this stage of flower anyways. Under the assumption that the situation isn't going to improve, is there anything I can do to help limp them home? They are supposedly a 56-63 day flower but I know that isn't anything more than a optimistic estimate. the tris are still all clear but I noticed couple hairs turning brown this morning. Is there anything I can do to maximize the potential of actually being able to harvest the worst off plants or am I handcuffed now and they aren't going to make it? Should I be removing the fan leaves that are dying so light can penetrate farther down to the smaller fans and sugar leaves that are still mostly healthy? or should I leave them there until every last spec of life is left in them? Should I remove the worst plants and arrange so I can get more light to the healthier plants? Anything i can do? I am so disappointed to get this far and then have it start falling apart at the end.

Also, I would be interested in opinions on the overall appearance/organization of the scrog/canopy. I had a lot of analysis paralysis when it came to defoliating which led me to play it safe and leave it a little thick. Is it too thick? .
