brown spotting on over watered plants

[emilya]

ok... I have been really stressing out over this problem.
First, the picture is attached to this note.

here is my setup:

What is your experience level? (first timer)
Your Equipment:
.1) Type and wattage of lights. T5 high output SunBlaze 48/8 - 6 blue bulbs and 2 red.. will switch to all red at flowering
.2) Distance from tops? approximately 4 inches
.3) Reflector type? SunBlaze fixture, individual reflectors above each bulb, mylar all throughout the box.
.4) Is there a consistent fresh air supply? Constant circulation, 50cfm fan at top of box drawing in from the bottom.
.5) Do you have an exhaust fan and a circulation fan? yes both, small circulation fan sitting at pot level blowing up into the light and across the top of the plants
.6) What are the bulb wattages, kelvin ratings, and schedule? 55w each x 8. 6-6500k, 2-3000k. On a 18/6 schedule
Your medium:
.7) Specific brand and type of soil, Miracle Grow 6 month formula 4 parts, 1 part vermiculite, 1 part perlite with 1/2 inch layer of vermiculite at the bottom of the pots.
.8) Size of container. 8" diameter x 7.5" height terra-clay pots
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings?
used paper towel method and planted directly to 8" pots.
Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting?
tap water, filtered with carbon filter, set out for at least 24 hours, ph 6.3-6.4
11) Method of checking water ph. (ph pen, test strips, aquarium test kit...)
aquarium test kit
12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...) not needed yet
13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. Miracle grow all purpose 24-8-16... only used once at 1/8 strength and saw nutrient burn, so have not used it again.
14) How often are you watering between feedings, and how much per watering? 2 cups, approximately every 3 days
15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) Planning to use molasses (unsulfered) after transplanting to 3gal buckets before flowering
16) Are your ph levels stable, or do they fluctuate? seem to be stable
17) What is your ingoing water's ph? ...your runoff ph? in-6.3, out 7-7.2 ( I think... not sure how to read since runoff is already a yellowish color)
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? Have not fed this way yet, but have tried seltzer water one time
Your growroom:
19) Indoors or outdoors? indoors
20) What size of closet, room or hut? box, 5'x 28"x4'
21) What are the temps and humidity levels while lights are on? ...With lights off? Temp, closely regulate 78-80 lights on, 70, lights off... humidity 30-35 off, 35-40 on
22) Have you seen signs of insects in the growroom? a couple of gnats, nothing else
Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?) 60/40 mix, white widow
24) From seeds or clones? seeds from Amsterdam seed company
25) Is this an autoflower strain? no

Look closely at the first true leaves. They are yellow and now have brown spots all over them. First, I know I hurt this girl with over watering. Because of that, and the miracle grow, this could be nutrient burn, but I thought this appeared on the edges and tips predominantly. What I am seeing is that the older leaves are yellowing and now I am getting these brown spots all over. I have been told that White Widow is light sensitive. Could this be burning as the leaves got thinner after being practically suffocated with all the water? It was also suggested that this looked like a MG deficiency. I got a water report, and MG is not even reported its levels are so low in my water, not to mention I am filtering. Would it be prudent to do an epson salt foliar feed very soon? I am open to suggestions.

ditch the miracle grow, fox farms ocean forest is way better and more affordable now. if im not mistaken vermiculite retains water so you most likely dont want that at the bottom of your planter. reduce temps a little and your ph may be too acidic if your in the yellow(based on the color chart for aquarium test kit). raise it a little. get through your miracle grow as fast as possible and spend a few dollars more and get quality to get quality. not funnin or nothing im just saying take advantage of the prices while you can.

Em do as Tank said in your grow log. I am sure that the miracle gro has Mg in it.
