Sorry i have no clue, but i start with the basics before i do anything drastic. Make sure ph is good, keep your ppm`s in check. Whats your watering schedulr like. Do you let the pots dry our before you water. Ar eyou keeping your temps in check

I am far from expert, but I would say its not from a defficiency, probably the opposite. I would try cutting down on the watering, let the plants suck up all the water before re-watering. Also would try diluting the nutrients a bit more than what it says and see if that doesn't help, then slowly increase to reccomended. It could also be cholrine/flourine burn, i assume ur using tap water. Take a large bucket or like 20 gallon rubbermaid bin (that hasnt had any chemicals in it ever) and fill with tap water. It is imperative that you let the water sit 24 hours before using, preferably in sunlight for as much of the time as possible. The air and sunlight will dissipate the chemicals in the tap water that are harmful to the plant. Do not under any cercumstance put water from the tap directly into hydro buckets. If you already know all this, sorry, I was just trying to help/be thorough.

Thanks for the good thoughts. I'm using filtered water (i'm buying it from meijer). The EC its 1.8, so I don't quite believe that I overfertilized them because thats not even full strength solution...I added some fresh water tho, so I diluted it.
Some of the leaves have those light brown spots on the leaf and also some small holes... COULD THOSE BE SOME SPIDERMITES? BUGS?

Now I'm using 0-1-2 (tsp/gal).
I also don't think is PH lock at all because as I said ... the PH is 5.8-6.2 all the time.
I just bought some bug spray for plants. I'm gonna keep on sprain them for few days and I'm gonna see whats up.
I don't know what to do about the nutrients. I added some water earlier to bring the EC a lil lower .... it is not the first time when I grow, but something like this I've never seen.
PS: from 4 plants, one does not have any spots like this, another one have them only on a couple of fan leaves and the other 2 .... pretty much

...everytime I see spots on foliage I think it's from overwatering, however I'm aware that other types of "lock out causes" can be responsible also.
...check out these pics, they are arranged in folders of plant abuses:

...do you use hydrogen peroxide in your h2o?
....good luck.

Just looking at this pics looks like PH lock....but thats imposible. I have a digital PH metter (a pretty good one) and the General Hydroponics PH tester (drops) so I can be as acurate as possible. the digital one is always showing me 5.8-6.2 and the drops color stais between the same range. So both PH tester are showing me a good range of PH .... 
I can't understand ...

Is this the same strain you've always grown? Those nutes sound a bit on the light side. I used GH 3 part on my last grow in soil (they were free so why not?) and used a stronger mix than that.
I would try SLOWLY adding more nutes over time and watch for positive or negative changes. The burns wont heal but you can keep the burns from spreading further.
Not sure if you have seen this but if not then it's another must read for GH users. Theres a nute calculator and examples. Helped point me in the right direction for feeding.

...myself, I'd try only run'n my pump twice per day...just to see if their's a difference...
...if you have any doubt in your ph meter at all, you should always have one of those liquid drop kits that they sell for pools and fish tanks....those will never lie to you (unless your color blind)
