I use the same by happenstance, and have for many grows with my old setup. The biggest issue I was getting is nitrogen abundance, clawing, etc., while seeing obvious signs of calcium/magnesium deficiency at the same time. I would frequently get nutrient burn, but even dialing my res back 10% would result in pink stems (phosphorus deficiency).
I mostly have things stable now, but the damage is done, it looks terrible.. but it's massive so I got that goin for me I guess.
Anyway, ultimately I changed how I was topping up my reservoir and things seem better, I am just not sure if I should try something else or not on the next run.
I have been using their two part connoisseur line for a while now, and it's generally set and forget. I would refill my bucket back up each morning to the same level, but didn't have to bother with ph, etc., and do a full replacement every 4 days or so. I tried that with aero at first and would quickly see deficiency signs, so then I tried just letting it run down and replacing res when it's low, but that resulted in crazy excess.
I added some additional lighting, which is helping it chew through more food, but the biggest change was refilling my ras back to roughly the same tds values a couple times a day, instead of once a day with a preset volume.
I am surprised you are PH'ing your water while running the ph perfect line. Does that have to do with running the full masters track? I didn't really have luck moving the needle the few times I've tried.
From my understanding, and the marketing propaganda, the surfactants and chelation make everything available for uptake as long as the range is > 4 and < 8ish. I genuinely stopped years ago, but I do miss the control sometimes.
