Gelato DWC SCROG (first hydro grow)

Had my first ph issue, was coming before I did res swap I believe. After swap at 60% nutients (GH) root zone is leaching into res raising ec and lowering ph. Chased the ph for a couple days with up and had still had full point drops. I added a couple gallons 100% (showing deficiency) solution to raise ec an recharged my torus module (should have done this at first flower res swap). I had added an additional air stone for an area of res I found sediment (was assuming precipitate of nutes), research said might have caused acid rain situation. I turned it off even an hour and saw no change in ph but left it off to take a factor out. Things are slowly settling, will not take any aggressive actions like a flush unless it continues a few more days. Until then, a bit of up and watching for obvious signs. Shout out to @hashy for being the only one to reply to my question and not jump to drastic measures immediately. Except the aggressive defoliation I just did during a wild ph swing... but it was that time and humidity is still high. Taking a big risk but she’s chugging along no matter what I do. Oh, and I added an additional spider farmer sf1000 today too. It’s at 100%. Am I mad? I ducted exhaust (now the t6 and a 4” vivosun from pre upgrade, both with filter) outside my room as temps are higher than I want and my ac is working overtime from the heat wave and having to cool heated air. It is a portable unit single hose cooling the whole room and I will be converting the intake air into the compressor to be ducted from outside (like a dual hose unit) so it is not using my cooled air to cool the air. And insulating the exhaust hose because it is radiating 113 degrees into my room instead of outside. Humidifier also dumping hot air into the room as I was putting the tent rh right back into the room. Hope these efficiencies allow me to control my environment a bit more.
