What the heck is MTF?
Where on the plant did it come from? Top, bottom, middle? Is your new growth yellower than bottom growth? What is your ph? How is the plant being grown? What nutes are you using? Add anything else you can think of. Why dont you add some pictures with the damage showing while on the plant rather than two dead leaves. I know what it is.

No, I am using (this is the last tank) Future 
garden stuff. I have used it for the last 2 years. I am changing over to the lucas formula GH Tommorrow
Here is a summary of my room.
1. Type of grow- hydro NFT (Homemade Areoflow tubes)
2. Age and strain of plants Bigbud, Been growing the same stain for 2 years now
3. Type and ratio of nutes -I use Liquid-earth nutes from FutureGarden.com at the rate of 1200 ppm ph of 5.8 Current NPK of: 178-131-327-??
Nitrate N NO3 155
Ammonium N NH4 23
Urea N NH2 0
Nitrogen N Total 178
Phosphorus P 131
Potassium K 327
Magnesium Mg 0?????????? Trying to find out now
Sulfur S 53
Calcium Ca 113
Iron Fe 6.34082
Boron B 0.00000
Manganese Mn 0.00000
Zinc Zn 0.00000
Molybdenum Mo 0.18494
Sodium Na 0.00000
Copper Cu 0.00000
Chlorine Cl 0.00000
Cobalt Co 0.00991
Silicon Si 0.00000
Selenium Se 0.00000
I also add 2 cups of Activator which is Humic Acid and Soluble Silicon.
I have 5 - 4’x8’ (32 SQ FT) tables with 4 tubes on each table. Plants are spaced 12” On Center
Each Table has Two 1000W HPS Hortalux Bulbs in 6” Vented reflectors Actual reflector measures about 20’ x 16” all reflectors are vented outside.
Each Table is filled with new Plants every 2 weeks SOG One time each cycle I fill 2 tables
Plants of Various ages are all feed the same nutes.
I use ONE 100 Gallon stock Tank for the entire room,
I use a Blu Ox Co2 Propane burner
A 24000 BTU Air Conditioner
A ½ HP Chiller
Now the environment:
Room Temp 75-85 Degrees
Humidity 45%
CO2 1500 PPM
Res Temp 68-75 Degrees
Total control is maintained by a computer (Growtronix).
Average Yield is 1.5 Lbs. a light
I have mother plants of witch I take clones every 2 weeks, Veg them for 2 weeks then into the SOG flower room.

Cool. You're probably a little low on nitrogen (N). This is normal during the latter stages of flower. Not to worry. Should be okay to leave alone. The plant should pretty much use up all of it's N by harvest. If it becomes alarming to you, then increase your nitrogen (N) slightly.
You're very close to flush anyway, right?

lol...
Leaf on the right looks like light bleaching...left side looks like a nute def/lockout.
Are all of the plants exhibiting the same problem or just 1 table or 1 strain or just a single plant?
Some pics of the entire plant would help greatly...
Since you've been growing this strain for a while, have you ever had stuff like this show up before with this strain? If so, any details about previous experiences would also help.
Is your phosphorus and potassium listed as p2o5 or p and k2o or k. To convert k2o to k multiply by .83 and p2o5 to p multiply by .43. The calculators will make the conversion for you I think. What is magnesium? We can look at the ratio of k ca mg. Also find out your zinc level. You are using alot of iron at over 6. I guess none of this matters since your changing ferts. Here is where to find the calculator at the bottom of this page: http://www.angelfire.com/cantina/fourtwenty/articles/profiles.htmfredfarts said:
