Ph and nutrients

I use Fox Farm Oceans soil. I was told that it had enough nutes in it for about 3-4 weeks. Other than micro nutes should I even bother giving it 'grow' nutes at about 3-5-1 or start feeding it 'ripe' which is 1-5-3, when I begin to flower. Can too much phosphorus cause a plat to finish too fast? I was also told that it's actually better to underfeed it a bit, any opinions?

In nutirent rich soil what Ph is good. Iwas told between 5.9 and 6.5. I usually try to get it to 6.2 or 6.3. is this too low for soil?
