hey you dudes having problems with salts, heres what I do and it works very well for me. I have always seemed to have problem with salts building up with autos. It is common with the autos. I just picked up an old reliable. EcoGrow. I use regular vegging nutes and don't ever seem to have problems with salts until the plants are flowering. When flowering starts I use 1/2 strength Ecogrow with 1/2 strength blooming nutes. The Ecogrow actually has as a side effect a lowering of salts to a degree. and I haven't had to do any major PH adjustments since I've been using it. I still check PH often but the Ecogrow seems to keep a leash on the salts. Remember, this is not a scientific study, just comments on my personal experiences. Good luck
