Question about Fertilized Soil

Hello Rollitup, new member/grower here,
I just bought some Scotts Garden Soil for my plants, and I was wondering if the fertilized soil will really last for three months without adding more fertilizer like the home-depot guy said it would.


Here is the NPK for it:
.08 - .05 - .05



Also, is there any other way to check the pH than by buying an expensive electric ph reader? I can't find out what the ph of my soil is, it doesn't say anywhere on the bag or website.

Here's the link of the same exact soil I bought:
The Scotts Miracle-Gro Company : Product General

Sorry if I asked a question that was previously answered, I'm in kind of a hurry.

npk sounds good

I know someone who uses that stuff and doesn't add a thing. Buds come out airy, he doesn't get the best yield, nd he uses a 1000hps I would reccommend using something for flowereing.

Oh, ok thats cool. I do have some Bloom Plus that I can use, it has a shitload of phos. Thanks
