Spots on a leaves?

Some details of your setup and environment would really help...with no other info, I'd have to guess PH probs.

Ph drops strangly from 6 to about 5 or less in just few days. I made it go up and its 6 now. I dont have ph pen but i check ph with a GHE´s ph test . I had a little bit of root rot, but I added hydrogen peroxide and roots look fine now.
The plants are in a aquafarm, coco with about 50% clay peebles. There is a air ring in water reservoir.
could it be nute burn, because I made nutrient solution 1 1/2 strengt. Ec 2.0-> two days and it´s 1.6 and still getting down.

Sure it could be a disease...but it's not likely. Most diseases and micronute def's are actually fairly uncommon if the environment and nutes are setup half-assed decently. Fix your PH and the spots will stop spreading.

root rot screws with your ph...ph screws with nutrient uptake...hydrogen peroxide...fix the rot

Its sometimes possible to tell whether you are getting microtoxicity issues by seeing where the spots are....
As with many leaf issues it also is important where on the plant the problem is.....
Normally when its a tox issue it shows not at the top of the plant but in older leaves.....
If the spots are caused by calcium def for example the spots would probably be more random....
If its a tox issue the spots will be largely along the veins and mostly on the downhill side of that vein.....
below the vein rather than above it....
I didnt get much from the pics....

snap. i think.
snap. i think.
does it look similar to this,
my ph is good, at 5.84 ish, ec at 1.9 water to start is .5.

This reminds me of a calcium and maybe mag def. I would say more than likely its due to ph . Maybe lower your ph to 5.8.

I am actually having similar problems with my soil plants. In fact, I don't even need to post pictures, the symptoms are exactly the same. Lower leaves are not affected, and it seems to affect random leaves in the middle to top. It's also sloowly spreading to random plants.
At first I was worried about mites, but close inspection revealed no evidence to support this.
My next guess was pH issues.
I'm gonna flush when they're dry and I'll let you know how it goes.
EDIT: I just flushed the affected plants. If they get better and the others begin to show similar symptoms, I think we've found the culprit dont ya think?

I have flushed the affected plants two times. Yesterday I gave some GHE 5-10-15 nutrient solution, and some Mineral Magic powder, and it could help a little. My friend is coming visit today and I think he could know what´s the problem. The buds are developing allmost normally, but the leaves are sad to watch. Oh, and the strain is Santa Maria, has anyone had same kind of problems with this strain?

have you checked ph of runoff. Are you using tap water, or RO. It kinda looks like a potas-cal-mag fight to me. BUt it could be PH fluctuation. MY advise is get a good PH meter and check your soil ph.
