I cannot get my pH to stay stable during final flushing. I am using ebb&flow watering 3x a day. I changed the 20 gal res last night to plain H2O w/5.8pH and let it run its course 2hrs before lights off. To make sure things were good, I checked the pH this morning before watering and it was 6.8. I adjusted back down to 5.7, and let the system do its morning watering. Lunchtime rolls around and same thing, 6.8pH. I dumped the res at this point thinking that maybe the salts coming off during the flushing was wacking out the pH. I have new water pH'd to 5.6 now in the res for tonights watering, but I cannot do this for five more days... Any suggestions?
