@Mike20132 @chefdave @the green bandit Apparently we keep missing each other this evening. Got another semi problem to ask about.......remember Mike, last night I asked you what the pH of distilled water should be........you replied around 7 which is what I thought......but when I tested it with my new meter it came up with a reading of 5.9! Even with Wally Mart 88cent distilled water, I don't think so! I then tested my county water.......8.92! Again, I don't think so! According to the county water commission report the pH averages 7.2-7.4! Decided to check calibration of pH pen......mixed up the 6. whatever solution stuck the pen in and pushed the calibrate button and held it for 5 seconds as per instructions.......nothing happened! It is supposed to flash 6. whatever and then stop on the pH........I think I must have a defective pen! It has a warranty of 1 year but I don't have time to deal with that crap, so I just ordered another brand from Amagone. It will be here Friday evening. In the meantime, should I just keep feeding the distilled water? The plants seem to be doing OK on it so far.
