Pound Town Auto (DWC, cabinet, first grow)

Switched to 20 hour light cycle on 2/8/24. Swapped res and mild cleaning on 2/10/24. Still adding GFF, but even at .5ml, it may have been too much given the concentration of the bacteria. Nutes still way too high and nitrogen toxicity started to show (pH 6.03, 1873us, 1.37 ppt, .96 sal, 65.5 F right after swap). After 64fl oz. water in the res was removed and a smallish pour of distilled water was added, the levels were still much too high. I didn't get back to try and fix the issue again for 2 days, but removed more water that day and diluted more and more over the next few days. By end of day 2/14/24, the res read at: pH 6.03, 1118us, 797ppm, .56 sal. 2/14/24, lights were slightly raised (were ~15"), and turned to level 5 reading at ~400ppfd and ~28dli.
