OK, I just finished taking notes on the Grow report #3. Zandor mentioned that some people adjust the pH levels at different cycles in the plants life (veg and flowering). So please clarify this and correct me if I'm wrong.
In hydro, the pH range is from 5.2 - 6.1
Nitrogen is available at a pH level of 5.5 to 7.5 (maybe even a little higher)
P is available at 5.6 - 6.5
K is available at 5.2 - 6.0

I know a plant needs more P than N in flowering. It seems to me that P falls in the same range as nitrogen. So what pH level is the best when flowering? When vegging?
