And the pH of your run-off water should be around 6.5. If your pH is out of range it will lock out nutrients causing a deficiancy. So adding more nutes would then cause more problems. So check that pH before you give any more nutes and get it fixed if out of range. I bet your watering them with tap water that has a high pH. A bottle of pH down is like 8 bucks at the hydro shop.Or if you don't want to mess with pH down the RO water I get out of the machines is right at 6.6, which would be close enough. :jointsmile:
