Har Har: Looks like you've got primarily an Indica strain going in the second thumbnail from the left on top.
If you're using good soil, go easy on the fertilizer. Miracle Grow is often the choice of newbie growers and it's good for a couple of months right out of the bag, but don[t over water it. Water by "the first knuckle rule," If you're into the dirt to the first knuckle of your index finger and it's dry then you need to water.
You'll want to consider a schedule like: water, feed or water, water feed. Put drip pans under your pots and don't over water until they start to fill like most people do. You'd probably be surprised by how little water your plants really do need.
You might want to investigate the Eco Pots out of Arizona. If you like to grow in dirt it's pretty hard to screw up with the Eco Pots. They're self watering by capillary action up. You have a fill tube at the top and a reservoir in the bottom, a separating plate, a couple of inches of vermiculite to hold the water and attract the roots down to it and a 20% perlite and 80% good potting soil mix. My plants love it.
If that reflection in your pictures is because you're foliar spraying your plants don't do it with the lights on. Those little beads of water become magnifying glasses and they'll heat stress your plants. You might also want to try half strength fertilizer for a while to see how they like it. I hope this helps.
