Ok, so I determined my plants had a nitrogen deficiency due to a lockout and now I want to make sure I'm doing this right. After I have flushed my plants and it's about time to water them again, what should I adjust my mixture to before I feed it to my plants? I know just to use plain water the first time, then half strength, then full, but should I adjust the ph of distilled water? I use Fox Farm's Grow Big right now, a drop of hesi super-vit in every gallon, and it seems that my ph will be too low with these...
It depends on the run-off pH and the pH of the water that you give it. Do whatever it takes to keep the run-off pH between 6.2-6.8.
