This is my first indoor grow its going pretty well so far I have some questions which I think are pretty basic.

I purchased my clones from the medical dispensary, (3 Purple Urkel, 2 Purple AK47, 1 Lemon Kush, 2 Mr. Nice Guy's) how do I know how old they are? Ppl on here refer to their plant life as day 1, day 2, ect. To me, my plants are on day 2 with me, lol So how do I tell how old they are? I submitted some pics.

I want to keep things pretty simple but I want to do things right as well. I am using black gold soil with cocoblend, I mixed it with perlite before transplanting them into 1gal grow bags, I use foxfarm big grow (1/2 tsp per gal every other watering) seems i'll be watering every other day. I tested the PH and its only at 1.25, should I worry about that right now or let them get adjusted first? Should I adjust the PH using the PH up chemical that you buy at the hydro store and add to the water? or is there something I add to the soil, (dolimite lime?)

Should I test for, or worry about nitrogen?

Whats the easiest/cheapest filter I can put on one of the exhaust tubes when it starts to smell?

I'm sure I will have more questions, any advice/tips is appreciated!!! check out my pics! its a 600w HPS light with a homemade cool tube using hurricane glass, a lot of tape, a 6'' inline exhaust fan, and a bathroom ventilation fan blowing cool air through the tube, works great. Its a small closet, 2x7.
