Too early to tell full damage to corals. Some of the harder hit corals are starting to extend their polyps so I am hopeful that the worse is behind me. "Fingers crossed, touch wood".
There is definitely a direct relationship between nitrates and phosphates. Each one controls the other when running low levels in a nutrient low reef tank.
From my experience when nitrate is the limiting nutrient (0 nitrate), poor colours and slow growth rate.
When phosphate is the limiting nutrient and has truly bottomed out bad things happen, much worse then low nitrates.
It is funny how some acros were not really impacted and others were devastated. Once I have a full grasp on the impacts I will provide a list of the corals and how they were affected in my tank under my adverse conditions.
Even though I suffered some serious setbacks I consider this experiment a success. Remember in the first post I said this was an experiment and I have kept all the data. I have learned far more than if I was just blindly lucky and had succeeded because I wouldn't have known why I succeeded.

I believe it's all due to the origin of the coral. I know Aussie SPS are from some of the lowest nutrient water, they need massive flow, intense lighting and ulns to be happy but others are from a more "dirtier" water like Bali might be a whole different ball game. We as reef keepers throw together corals from all over the world with different water parameters and expect every single one to be flourishing but that's just not possible. If 3 out of your 20 corals aren't happy and the rest are doing great, I think it might be time for you to re-house those 3...I am glad to hear everything is on a rebound. I will be expecting picture update soon!
