Hey dude,
FWIW - here is my .02
First, I think those clones look well and ready for a transplant. Get them into whatever medium you have chosen (soil is the easiest), get some decent nutes, start off with only 1/2 strength solutions, and get those girls vegging. Figure you have at least 3-4 weeks of vegging ahead of you before you are going to flip them 12/12.
I would advise against getting more clones right now. First figure out how everything works in your current setup (i.e. your current girls are your experiments) and then when you know how it is all working, starting getting more seeds and/or clones.
If you are growing using tap water, good nutes, good soil, you probably don't need a ph meter. I use one because I have well water, and the ph can vary at different times of the year, but most of the water coming out of a city tap stays pretty standard year round. If you want, pick up one of those cheap aquarium ph testing kits (the one with the litmus paper). You can take a first read, set things up, and you are done. Save the money in not buying the ph meter and use it to buy lights and nutes.
A 400W HPS is a great light to have. I have used one in all my grows. However, depending on the size of your grow space it can heat things up. Venting is important. Consider building a Cool Tube for the bulb.
Also aroma control is something that has to be handled.
I do agree that a temp/rh meter is very important, however be aware that the temps in your cab will vary greatly depending on where you place the thermometer. In my cab the temp can vary by up to 12C from the bottom to the top of the canopy. Try to tweak the temp for what is best up at the canopy.
A SOG is great, but depending on your space you might want to consider a ScrOG. I am a recent convert and intend for most of my upcoming grows to use da screen. It allows you to get a good yield, with a minimum number of plants.
Oh yeah, one more thing, use the largest pots you can to grow your weed. I use to use 1gal bags, but my recent grow I went to 3gals. What a difference! Weed likes to stretch out its legs. Give those girls room!
Good luck with the grow.
Peace.
