How long has this problem been going on? One Week
What STRAIN are you growing? Lambsbread
What was the establishing technique? (seed or clone?) Clone
What is the age of your plants? 2 months
How long have they been in the soil mixture they are in now? 1.5 months - FFOF
Were they in the same mixture when they were seedlings/smaller plant? If not, what mixture were they in before? I'm not sure what mixture they were in when I got them from the dispensary, similar looking to FFOF
How Tall are the plants? LSTing so hard to say what height would be but average canopy height is 13-14" from top of container.
What PHASE (seedling, vegetative or flower) are the plants in? Flower
What Technique are you using? (SOG, SCROG etc) LST
What size pots are you using? (Include how many subjects to pot) 3 gallon pots, one plant per pot
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) %100 FFOF unamended
What brand Nutrient's are you using? Aerated Compost Teas and Bio Bizz nutrients
How much of each nutrient are you using with how much water? Fed with an ACT two waterings ago and fed with regular nutes again this past watering. Past feeding was 1 tsp topmax, 3 tbs maxicrop fish emulsion, 3 tbs maxicrop seaweed, 1 tsp organic blackstrap molasses, 3 tsp bio bloom all mixed in a gallon and divided evenly between the three plants
How often are you feeding? Usually every other watering but I was trying to hit the plants hard with nutrients because of what I thought was a N deficiency
If flowering, when did you switch over to using Bloom nutrients? As soon as I made the switch to 12/12, using this chart here, http://www.thctalk.com/gallery/data/571/BioBizz.jpg I'm substituting fish emulsion for bio grow
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect) I'm mixing them all together and feeding at same time as per feeding chart listed above
What is the TDS/EC/PPM of your nutrients used? Don't know, doesn't matter - organic
What is the pH of the "RUN-OFF"? Haven't tested it yet and want to let pots dry out as I suspect I might be overwatering.
How often are you testing pH/ppm/EC/TDS? never
What method of pH test was administered? Using Strips? pH pen? I haven't tested but I will next watering with pH strips
How often are you watering? twice a week
When was your last feeding and how often are you feeding? fed them three days ago
What size bulb are you using? 400 watt
How old is your bulbs? Don't know, probably on the older side 3 or 4 years rough guess with a growing time of a year when added all together
What is the distance to the canopy? +-13"
What is your RH Factor? (Relative Humidity) Extremely low, often too low to register on my thermometer
What is the canopy temperature? Usually in around 80-82
What is the Day/Night Temp? (Include fluctuation range)75/82 - Day/Night
What is the current Air Flow? (cfm etc.) 6" vortec running at 2/3 capacity
Tell us about your ventilation, intake exhaust and when its running and not running ? 6" vortec running at 2/3 capacity for exhaust with a 6" - 25W - 188 CFM booster fan running at 100%
Is the fan blowing directly at plants? intake is a duct pointing into the tent with a small fan underneath intake airflow directing it upwards. There is a small fan clipped onto the frame of the tent blowing air across the canopy.
Is the grow substrate constantly wet or moist? No
Is your water HARD or SOFT? hard (rocky mountains)
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? - Tap water aerated with air stons for at least several hours to dechlorinate
If using tap water, what is the ppm/EC/TDS of the water right out of the tap?(Only if you have a tds pen) don't know
If using RO,Distilled,mineral water, what is the ppm/EC/TDS without any additives?(Only if you have a tds pen) don't konw
Are you using water from a water softener? no, tap water
Has plant been recently pruned, cloned or pinched? no
Have any pest chemicals been used? If so what and when? no
Are plant's infected with pest's? Not that I'm aware of, haven't seen any in the tent.
I realize I could have over fertilized the plants but I was trying to address what I thought was a N deficiency with possibly some lack of P as well. What is odd is that it affected the three different plants at different times. One started just over a week ago, then the other a day or two after that and then finally the third is showing the same signs. The problem has started down low on the plant and is slowly working it's way up. The fan leaves start to yellow and develop brown spots and necrosis before being "eaten" by the plant. As you can tell by the pictures the canopy looks perfect but I don't want this to progress and work it's way up the plants.

The next three pictures are all from the same plant, the one in the foreground of the canopy picture above. With different signs from different leaves.
This last picture is a group shot of different leaves pulled off of all three plants. All the leaves are the lowest on the plants but this problem is working it's way up the plant.
Finally, here is a link to my grow diary thread in the organic soil forum if you want to read it to get some more background info. Aside from that if you have any questions then let me know and I'll get back with you as soon as possible. https://www.icmag.com/ic/showthread.php?t=216629
Thanks Fellahs.
*EDIT* I didn't mention the thermometer says it's 88 in the picture but that is the hottest it's ever been and rarely get's above 83-84 degrees. Also, it says 16% humidity but that is the lowest the meter will read to. My other gauges just says "low" and the lowest it will register is between 20 and 25% humidity. So I don't know exact humidity other than it being very low.
