Aim for pH 6-7 though out the plants life. Young plants and nutrients, little plants require little nutrients. The flowering stage, either natural or photo period enduced is time to change NPK. Go to low N with higher P and K, during this time.

Change the PK(up) just before flowering and buy some Ph UP from your Hydro shop.

You don't want to raise your pH unless below 5.5, marijuana grows best with a slightly lower Ph.

stays relevant.
Soil should be around 6.5pH
Hydro should be around 5.8pH
You can change your NPK ratio with the Dutch Nutrient Formula 6 pack
You can purchase pH up/pH down from Home depot for about $8.00 per half gallon.
