pH in the tank is steady at 5.8-5.9

when I did the clear water rinse and checked pH of the run off it sat around 6.2 -3 Good solid numbers in the right places.

they seem to carry a fickleness to them on the pH I am thinking. meaning they probably have a different desire as in pH level than what they are getting. so they are not as happy as they could be. Or could be back to initial fertigation, toxic shock sometimes lingers and they don't make it or they are like this, ornery and miss understood. Ha
