Ok so I have been reading reading reading for several hours a day and am buying everything to grow in couple weeks here, but i have a couple questions that werent clear in the threads i have read:

1. When testing pH is it just of the water being poured on the plants? or does the soil actually have a pH?
2. Whats topping and pruning? is it just cutting off the main cola or branches so they turn into 2 so u have a shorter bushier plant?
3. Is it possible to do an entire grow without using ferts? in a 3 gallon grow bag?
4. How neccesary is a ec meter or wat is used to determine ppm?

Thanks for your help, soon I will post pics of my grow closet which will feature a 4' 6 bulb t5 system with 10 plants of white satin (mandala, low odor), I figure that will be enough light to make it to flower and then when i throw out the males so it should be enough light!
