Some of your plants look real good, bro, and some of them look not so good.
You're experiencing some of the hardships that I learned from the hard way, too. Just remember to keep a positive and patient attitude and things will work out.
I see you're struggling a lot with cloning. I had hell, too, with my first several batches of clones, but now I have absolute success with them. Here are the things you need to remember...
Clones cannot feed from the stem, so make sure you mist them regularly and keep them in a domed environment with humidity but not too much heat. My first few sets died from heat. Also be sure that they're in the same light that they were prior to cutting to minimize stress.
Make sure you cut at a 45 degree angle so water droplets don't get stuck in the 90 degree pipe shape and smother your potential roots, and make sure you get that bad boy in to some rooting gel right after cutting to minimize risk of air bubbles. It's important to cut near a node so you can peel the little side branches off and expose that part of the stem to the rooting solution.
Otherwise, they're going to look real bad at first because of the stress, but as long as the plant material stays fleshy and green they're going to live. It's all about moisture!
Lastly I have noticed a lot of stretching and lower drying on some of your plants. My opinion is that your awesome plants are right below your lights and your stretching plants are too far from the lights. Make sure you water those ladies often enough and keep them flowing with nitrogen to avoid those lower pale green leaves.
Hope I've helped! Best of luck, dude!
