Are we certain there are no spider mites in this grow? Those spots could be where the eggs and hatched mites are causing deficiencies but with how much I see, I would also expect to see some webbing by now, which I cannot see, but it is a little hard to tell. A closeup of some heavily affected leaves would help us get a more determinate answer.
I have been on 24/7 veg for a while now. I was 18/6 before, I like them both and to be honest I don't see huge differences between them, plant training and root vigor are much more important for growth rate and health than light cycle, in my opinion. I used LED shop lights with the highest umol output available, I tested about 10 different brands before settling. Root growth does happen at "night" but as stated, like they do in Alaska during the endless summer, the plants realize quickly they have an unlimited photon source, and they won't *not* make use of it just because they weren't started in that cycle. If that makes sense?
If it isn't mites, I agree looks like Ca deficiency, given the uniform spread of the dots. Some comments I've seen over the years on RIU detest the use of calmag (they like to use epsom salt and pickle crisps, among other things) but whenever my clients are showing a deficiency, the CalMag from botanicare has never failed to remediate the issue. I run it at 5ml/gal for veg and bloom so as to not overdo it, this prevents lockout and mineral buildup, my runoff pH is very stable. If a plant is showing a lot of deficiency across the leaves (where it gets bad enough such that the plant looks like it has a rust infection) I go to 10ml/gal for 1 or 2 feed cycles (only for the affected plant ofc, not all plants in the room)
I hope things continue to work out, it's looking good.

I'm flattered.
