I'm not sure why, but I'm getting some brown spots and yellowing on my young plants.

What is your experience level? (first timer, novice, experienced...) I've done an outdoor grow and an indoor, so still learning.

Your Equipment:
.1) Type and wattage of lights. (MH, HPS, CFL's, tube fluorescents, LED's) 1000W MH and 3 T8
.2) Distance from tops? MH is almost 2 feet and the florescents are about a foot
.3) Reflector type? (cool tube set-up, bat wing, enclosed reflector, bare bulb...) Bat wing on the MH and just a regular shop light for the T8s
.4) Is there a consistent fresh air supply? Yes
.5) Do you have an exhaust fan and a circulation fan? I have an exhaust fan and a portable AC for my circulation fan.
.6) What are the bulb wattages, kelvin ratings, and schedule? MH is 1000w and the T8s are 32W(I believe) and schedule is on 7am to 1am

Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...) Fox Farm Ocean Forrest, nothing added.
.8) Size of container. They're small containers, not 100% sure.
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings? No

Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting? Tap, ~7.2
11) Method of checking water ph. (ph pen, test strips, aquarium test kit...) Pool PH/Chlorine test kit.
12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...) I don't think that I need to adjust the PH(Should I?)
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. I'm using Earth Juice Grow, Catalyst, and Bloom. Grow is 1 TBSP, the others are 1 TSP per Gal. Feeding schedule was every other, but now It's about twice a week.
14) How often are you watering between feedings, and how much per watering? I'm watering every day, so about 2-3 times between feedings
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) None.
16) Are your ph levels stable, or do they fluctuate? I've only periodically tested my PH, and it's been consistent within a .2 range.
17) What is your ingoing water's ph? ...your runoff ph? Ingoing is ~7.2, I don't know about the runoff.
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? I don't.

Your growroom:
19) Indoors or outdoors? Kind of a hybrid, it's in a shed.
20) What size of closet, room or hut? 10x10
21) What are the temps and humidity levels while lights are on? ...With lights off? Temps stay around 78-82, and around 45-50% humidity.
22) Have you seen signs of insects in the growroom? I did in my last crop, however before starting these new ones I scrubbed the room down with organic insecticides

Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?) I'm not sure about the blend, however, it is a Northern Lights strand.
24) From seeds or clones? Seeds
25) Is this an autoflower strain? No it isn't.

I had multiple problems with the first go around which lead to just under 3 ounces for 10 plants, so I'm really, I mean REALLY looking to avoid that again in this one. I've got 16 plants going in this one, however the 16th is a random seed found out of a bag.
