Northern Lights Pot Noodles + 2 autos

So something went wrong with the feed at some point - either the pH meter calibration was wrong or I measured something wrong but I hurt the little ones quite badly very early and now they're all still recovering. I am giving them a foliar spray of CalMag at 800 µS/cm twice a day and try to do everything right with the feed but still am not in a good routine of getting the numbers right. I think they are now doing better but they are way behind and hopefully start growing well soon.
