personally, i like less of everything near the end, especially if the plant is all green. i up the ful power, slf, and even mp and lower everythingelse, and let the plant, enzymes, and bacteria dictate what the plant uptakes, if its all green there is probably enough to get to the finish with just some HH flushes and microbes.
all that sed, you seem to have something going on, so go with your gut. i just personally dont like an all green plant at the end, i like some colors, terps, etc, and 'ripening' does this naturally - so less is more, and drop the temps at the end. do a very dry cycle, then do a very wet cycle the next week, try to hurt the plant, and it will send out all its stinky defense mechanisms. that to me, is what affects the plant more at the end than anything else in an indoor setup.
