As Orzy said Foxfarm is nice stuff but you will pay for it. And if they don't have a store that carries it where you are at then you pay out the bung for shipping...
No matter what soil you use with whatever pH it is, once you start adding fert's etc. the pH will most likely change after a while, so you will want to adjust reguardless. Some can grow without their soil pH changing much however.

Nurseries can have some good stuff, then with a trusty pH meter you can adjust. But if you guys are talking about a soil tester you stick in the soil then forget those, they are junk.
