Is this LSF?

I've had brown rust problems in the early days when I was in hydro, but that was because I couldn't control the pH and it was swinging madly (rhizo, airstones, silt) - so pH can totally do that to your plants.

At the moment they're all looking much healthier and it hasn't spread, so perhaps it was a pH problem. Weird, but am happy....

whatever it was im glad its subsiding.
still dont think pH was the direct result tho....

as long as they are returning to levels of your liking, thats what matters.

or ye sure its not beginning of nute burn, slight yellowing on leaf margin, some distorted leaves, my first option would be do a wash out and then half feed. safest option if ure worried about crop.
