Here is the Q and A form. Hopefully the additional information will help somebody to diagnose my problem. I had to chope down the one plant that was dying. Now after a few days one of my reaming three plants is beginning to show symptoms of something going wrong. I don't know if it's the same problem. I will attach pictures.

What is your experience level? (first timer, novice, experienced...)
this is my first grow

Your Equipment:
.1) Type and wattage of lights. (MH, HPS, CFL's, tube fluorescents, LED's)
I have one 150w HPS and one 400w MH

.2) Distance from tops?
The MH is angled and kind of aiming in on the plants from above and in front of them. I put it there to get light farther down the plants. The 150w HPS is directly above them about a foot from the top of the plants (maybe a little less).

.3) Reflector type? (cool tube set-up, bat wing, enclosed reflector, bare bulb...)
The 400w MH has a bat wing and the HPS has an enclosed reflector

.4) Is there a consistent fresh air supply?
they are in a closet, but I open the door when the lights are on and there is always a fan going in there

.5) Do you have an exhaust fan and a circulation fan?
I have one fan on the floor in front of the plants aiming up towards their tops. It keeps the plants fluttering a fair bit. I did this to make sure the tops of the plants didn't get hot from being too close to the light.


Your medium:
.7) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...)
I am using the fox farms ocean soil stuff. Can't remember the name. It's in the light blue bag with fish on it and it says something about ocean crap.

.8) Size of container.
the plants are in one gallon pots

.9) Did you use peat pucks (or similar) to root clones or germinate seedlings?
no, I planted seedlings in miracle grow seed starter in jiffy cups and then moved them into the soil pots. The soil consists of vermiculite (whatever that shits called), seed starter mix and the soil I mentioned above. The blend is about 50% soil and 25% of each of the other too to help the plants breath and the soil to hold water.

Your nutrients and water:
10) Source of water? (tap, bottled or filtered) What's it's ph before adjusting?
I am giving them tap water. I fill a big bowl and let it sit for at least a day though

11) Method of checking water ph. (ph pen, test strips, aquarium test kit...)
I'm going to catch holy hell over this. I haven't actually checked the ph yet. I have a ph meter at work I can bring home to check it though. I plan on bringing it home tomorrow.

12) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...)
I haven't ever adjusted the ph

13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule.
I am feeding them with Open Sesame. It is distributed by foxfarms. The NPK ratio is 5-45-19. I feed the plants every other day. Recently I started adding in a tad bit of my veg fertilizer as well. It should be a pretty insignificant amount though. Like a spoon full in a gallon in a half of water. With the open sesame I am putting in one to two table spoons with a gallon and a half of water.

14) How often are you watering between feedings, and how much per watering?
I only water when I feed them

15) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...)
no

16) Are your ph levels stable, or do they fluctuate?
don't know

17) What is your ingoing water's ph? ...your runoff ph?
don't know

18) Do you foliar feed? If so, with what, how often, and at what time do you spray?
no

Your growroom:
19) Indoors or outdoors?
indoors in my closet

20) What size of closet, room or hut?
It is a walk in closet. Probably 5ft by 6ft

21) What are the temps and humidity levels while lights are on? ...With lights off?
lights on its about 80 with 50% humidity. lights off its around 65-70 with the same humidity

22) Have you seen signs of insects in the growroom?
nope

Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?)
white widow

24) From seeds or clones?
seeds

25) Is this an autoflower strain?
no
