Starting the flush today, still a bit of brown spotting appearing here and there but harvest isn't far away so i'm just rolling with it now. Got myself a 'Govee' wifi thermometer/hygrometer this week so now i can check the readings on my phone from anywhere and have set alerts up for when it goes out of my preferred range. Only had it a couple of days so will update next week on what it's like but no issues so far.
