cause the plant still needs nutes but because of the ph the nutes you were adding were just building up in the soil making your ph problem worse. so you flush to get all the built up salts and what not out then start fresh with soil with the right ph and the right nutes and the plant should respond.

I am having the same problem but i am growing Hydro. I am using Foxfarm nutes with Liquid Carma and SubCulture. I check my ph every morning and it is usually at 6.8 and i bring it down to 5.7-5.8 The ppm is at 1150 in veg stage. I have rust colored spots on some large fan leaves.

is it calibrated or does it even have a calibration on it? if it does that might be off, or your soil was way above 7 and it barley brought it down to 7. did you flush it right, if you didn't flush enough their still might be too much stuff in the soil.
