Should I be worried?

The pH is causing lockout I understand that soil buffers pH but the buffers eventually wash out. Honest. Push PhD 5.8 - 6.2 water through the pots until the run off shows the same pH and the ppm is around 700 - 900 then LIFTA for a while until the plants recover. Once they bounce back feed them low amounts of nutrients as the soil has nutrients in it anyway. The idea is to keep the pH and ppm in a range where the plants thrive.
