Mg deficiency or Rust fungi!!
weird one here, I think that cal mag might help, look for bugs under the leaves and on the steam too, also it will be a week or so till you see results of calmag, since damage starts at the roots first then up, some healing might be happining already. its good that you have the hygrozyme, keep using that it will help thoughs roots. keep us posted, if you want to take care of any fungus sulfer is good and cheep, and should be used any way, at least once in the grow, if not a few times or even once a week or once a month, untill a week or 2 before bud start to show up.also foiler spraying some neem oil regularly might help next time, to keep from getting this, However it does look like a deficiancy, but only time will tell. hopefull that calmag will help,

By the way this is a link to my grow log for more pics and a little more background. Once again Thanks for all the help I'm getting on this problem.:thumbsup::thumbsup:

Thanks for that link,.... it's bookmarked now! ;) :hippy:

Yes, that is an awesome link, bookmarked myself. BUT I don't see any picture that looks right for this. I still stand by the RO water as the issue and loss of micronutrients. I had the problem with RO and stopped RO and the problem went away. It was diagnosed as rust fungus by several. It is gone from my garden since I went to straight tap water. That is the ONLY change and that is why I attribute the appearance to the absence of balanced micronutrients in the water.

no problem guys, I agree I dont see anything like what were looking at. I think their is some kind of other thing happening here fungus or desises of sort, a weird leaf indeed.

In my garden, if the ph get's too high, I get the "canoeing" of the leaves. (not to be confused with "the Claw, which is a low ph issue) Your new growth looks awfully yellow compared to the neighboring plant.
You mention using phUp and phDown. You shouldn't need nor use both, and if you do the ph will bounce to extremes. Keep ingoing ph steady and trust the buffering of FFOF. At least for the first couple of months in the stuff. Once the buffering depletes, you'll notice the yellowing, the claw, and nutrient lock-out. At that time, raise the ph of your ingoing water by a couple of decimal points, and watch for any reaction. (from 6.2 ph to 6.5 ph, for example)
Are you trying to use the test drops to determine runoff ph, and are you trying to adjust your ph accordingly...? If so...stop. You can not determine accurate runoff ph with the test drops. The tinting skews the color-coded results. Same goes with trying to ph the water after adding nutrients. My wellwater comes out at 7.9ish ph. I use phDown to adjust water to about 6.8 or 6.9, then add the nutrients. This brings down the ph to 6.2 or 6.3ish.
Are you sure you're not giving any additives or foliar spraying? (this includes the recent past) No Superthrive or tea's or anything you've mixed yourself...? Looks a bit like heavy metals poisoning, but I'd try maintaining proper ph before doing any other damage from poisons and crap.
When watering or feeding, are you sure you are getting water down to the lower root zone? If you never do, I'd flush well with properly ph'd water, as you might be getting salt build-up. I use Fox Farms nutes, and perform a monthly 'maintenance' flush just for this reason.

Alright guys thanks for all the help and advice. I've had this issue corrected for about a week or 2, but was waiting just to make sure. Since I had the Cal-Mag first I started it out on that while I was waiting on the Sulfur through the mail. By the time the Sulfur got here the problem was solved on the new growth. So I guess the Cal-Mag worked. I still haven't used the sulfur and the problem is gone on all but 1 of the plants. That one plant does look a ton better, but it just won't go completely on the mend. All the leaves that were affected had to be pruned off or they died on their own anyways. While pruning I did notice that the leaves were affected starting at the fan leaves on the bottom and then moved up. I also noticed that if I pruned 1 fan leaf off if I looked for what I call the sister leaf(exact opposite leaf on other side of plant) it would be affected as well. That tells me it was coming from inside the plant. If it was fungi it would have spread around the plants in an almost random pattern. So once again thanks all for the help. Mg and other micronutrient difficiency was the WINNER.:thumbsup::thumbsup:

Maybe this was low calcium. An important one to remember. Thanks.

NO, it was a micronutrient deficiency....particularly calcium and magnesium.
RO water pulls all the good and the bad out of the water....IF you use RO you need to replenish the micronutrients.
Thanks so much for posting your findings. :thumbsup:
