I learned this week, though I probably should have known already, that water sitting in a jug experiences pH chances. My Jack's 321 solution I had pH'd at 5.8 was up to 6.8. The girls didnt have a great week and I suspect this is why. The "Sick Girl" from last week is now my strongest looking plant I think. I have also connected an AutoPot system, though I cannot turn it on, I can use it as a water hose for feeding time.
