I would not worry about ppm. I have never used the nutes you r using. I do not know your experience. How long have you been growing? Soil is pretty easy and simple. The last thing you want to do is change a bunch of stuff at once. Changes in soil happen slower than other mediums i.e. problems and cures. most people suggest a flush first because you will be leaching out the salts and starting fresh when you do make changes. I still think root bound is causing some of the problem. But flowering plants react differently than vegging plants. Do you know the ph you are feeding them at? The reason not to take off fan leafs is because of what I said before. Those leaves are taking the brunt of the problem and if you remove them the problem will move to the next leaf faster. Have you studied up on the nutes you are using?
