So here's some more thoughts (cut and pasted from my journal): ... if I recall, the last grow had these problems too. All pots then were MG. But it was complicated by a) red spider mites, b) no additional fertilizers to speak of (as opposed to this grow), and c) some neglect, so I'm not sure a direct comparison is possible, though it does seem like it's related based on symptoms and that both were MG.
The MG bucket, this time, also got dolomite but nothing else until I started giving MG Bloom Booster at flowering, every other watering along with all the rest of the buckets.
The other plant in that MG pot is STARTING to show similar signs.
All three other buckets are filled with SPENT MG from the last (4 month)grow, plus 25% worm castings and dolomite. None of them are showing any signs of nutrient/health issues EXCEPT for the other big sativa-looking girl, who is showing a LITTLE bit of the same. It might not be worth correcting this one, I dunno ....
So, I get you want me to flush, Hawk, and I'll be glad to give that a go but what do you think is the diagnosis? I was giving half concentration MG Bloom Booster at half strength every other watering (so nutes once a week), and starting EC (I presume) for the water is about 0.44. I'm not sure it's calcium deficiency. There ought to be enough present but perhaps it's locked out? Do you still think I need to adjust pH?
Here's a couple pictures of pH testing I did today.
a) tap water
b) other four bucket's runoff (water only)
Edit: come to think of it, as I look at all those together, the runoff looks a little acidic, eh?

Well I never claimed it was Calcium. That's not so common indoors.
Is this only affecting the lower leaves of the plant? Middle leaves of the plant? Is it spreading? How many of the leaves is it affecting.

PoloDown suggested that.
It started showing well into flowering, so from mids up. Old leaves (lower third) are good. New leaves look healthy but start showing spotting and progresses from minor spots to yellow spots to brown spots. The picture in my OP on this topic shows it (some are worse than this now).
It's pretty much of the leaves. No dead leaves yet but it'll happen, I suspect. There's also crispy tips and cat-claw (?), or "clawed", undercurled leaf ends.
Here's a couple pictures from today. Sorry for missing better detail. Please refer also to the OP.
Most of this is the plant in question. The other plant in the bucket is a 1/4 the size of the big girl.

Based on a review of my photo collection, it seems I noticed the symptoms about March 10. Here's a good photo from then.
Edit: to make it easier to see the progression I just post both photos here. They are from the same plant, a week apart. There are some worse ones.

That is defiantly getting worse! So whats the final diagnoses?

I'm sticking with that they need to be flushed, and that you just have a sensitive strain.

How do those runoff pH readings look to you?

Fine. pH in soil doesn't have to be exact. I've known people to never pH and they dont have issues. Maybe they're luck, I dunno. I personally just try and get it close

Fuck them strips! what you have to let them dry out too read ? Most growers i know use pens ! I have a cheaper one but it works on the money. I checked it, cal. it. Easy to use. I should be a sales man. nan

I don't know, Wannabe. I'm willing to bet those strips are as accurate as a "cheap" pH pen. But you should define to me what you mean by "cheap". You can also check those strips against known solutions to "calibrate" your reading of them. I did this, of course.
Way back in the day, in college chemistry and other science laboratories, we used pH paper. We didn't have fancy electronic meters (well, maybe the prof's did for their own use).
Notice the tap water measurement roughly matches the results of local water from a professional lab. Not to say a high quality pH meter wouldn't be nice to accurately measure +/- 0.1 or so ....

Well, I suppose this will have to remain a mystery. No time to realize a recovery because they're all coming down! Harvest time!
