A Few Basic Questions

Okay - I've grown pot before, but this will be first time trying hydroponics. I'm going to try deep water method with a 4 gallon reservoir using fox farms grow big

My questions are the following -

1) What is the PH that i should aim for? I THOUGHT it was 5.5 but now I'm seeing different things

2) Will I be okay using only Grow Big fert for vegging, and Big Bloom for flowering? Those two are adequate for everything, right/

3) Using this deep water method, is it true to always use 1/3rd strength fertilizer solution? (For example, the fertilizer says 1 tsp/gal...so i should only use .33 tsp/gal instead?)

I know these are basic questions, but I really want to make sure I know what I'm doing and get this right. I'm sure I'll think of some more .
Thanks guys

Sounds good, Man!

1. High five! (5.5 - 6.0)

2. Those basic nutes will work fine. They have some additives that you can try later.

3. It's best to use less than the label, until your plants ask for more.
