Hi my ph runoff is 6.8 even tho it goes in at 5.8 and my ec runs off at 2.7 even tho it goes in at just over 1.1, i have tried to flush it with low dosage of nutes but run off on next feed is still the same. I have tried lowering ph to 5.5 but run off still comes out 6.8. Only using canna a+b and little cal mag but not all the time
