I've been growing for some time now I currently use Active Aqua ebb and flo 8 bucket, 4 spyderfarm 4k series in bloom, and 2 spyderfarm 2k series in my veg. I currently am having a Ph problem in my cloner ez-clone 30 site. I have used this cloner for about 8yrs with great success, but now for some reason my water is at 9.1Ph. I use RO water in my cloner as I have done the whole time, but now I have lost 2 sets of clones back to back. Can a dirty RO filter cause the water Ph to raise? Thank you for any help.
