ok so I see you've already thought of those possibilities which I forgot about since reading the thread yesterday.
Doesn't look quite like the pictures of a calcium deficiency but it's possible as I've never actually seen one in real life although I don't understand why that should be the case if you're giving them a good dose of it.
pH sounds good too, how are you checking it? Pen, strips, drops?
How much runoff do you have compared to how much water you put in?
How quickly did it appear?
Early in my current grow when I hadn't been watering to runoff much yet as they were still pretty small I had some sort of similar leaf problems on the biggest lower fan leaves. They appeared overnight as like green indents in the leaves which quickly turned into yellow burnt looking bits and the leaf ends dried up and would crumble if I squeezed them. I started watering with good runoff, cut the leaves off and that was the end of that. Turned out my pH was a bit low in the medium itself but not on all plants, I had been collecting the runoff water from all 4 plants and putting it in one bucket and testing the pH. I now collect the runoff water and test it all separately and have found out the pH can vary by up to about 0.5 between the different plant pots despite them all getting the same pH going in. the average pH with the combined runoff was good but the individual runoff was off in two of the pots.
Not sure if that sort of thing applies to you but that's also a possibility

Thats helpful! I give them a good amount of run off 20% plus... but i collect it in a bucket as you said... it comes out around the same it went in at 6. I test with pen and then with drops to make double sure. Ill have a look individually. One thing i was doing after seeing issues was when watering alternatively, i was giving calmag+nutes and calmag+ freshwater? Not sure if this was too much?
it appeared pretty much overnight which was strange.Comment
