This week was an absolute nightmare .
Had what I'm guessing is bacterial issues in my res, massive pH swing and early stage lockout .
Switched from deionised store bought water to a 0.2 micron activated carbon water filter and I'm guessing it knocked her about a bit
ph was over 7 in my Autopot bases .
Flushed thoroughly with pH5.8 water and brought the nutes back in at 5.8
