I would def stop mixing zone and h2o2 and thats probably what burned those tips if I had to guess.all that h202 can make your ph go crazy as well.plants look good in those last pics.i would do a res change and go for 800 to 850 ppm and 5.8 ph and see if it stays in check better.and I would skip the zone and h202 for a week or so see if they respond well.low ppm will have them drinking like crazy and ph will swing as well.gl
