Runoff PPM's are higher and Ph numbers are lower than what I've been adding when I water-

I’d be concerned with the strength of your feeds - the EC/PPM in general. You’re hovering around 1500 ppm which is a very strong feed, especially for autoflowers. I rarely go above 1000 PPM with photos. You are starting to see some signs of lockout on a few and one has some signs of N toxicity (SD2). I’d personally do a flush with reg water and run a solid gallon or two thru the bottom of each.. cut those feeds in half going forward. Advanced is so “complex” of a line up I don’t know what to tell you to cut out of that regimen but I’d be feeding 650-800 max going forward unless there’s signs of deficiencies.
