possibly calcium deficiency. I’m leaning more towards this
Any Ideas What’s Going On?

Yes, usually those spots would indicate calcium lacking. Light burn wouldn't do that. As for the edges curling up, again, likely not light, but more of a heat issue or possibly low humidity. Too strong of a light would either burn the leaves or bleach them.

Humidity is around 55/60. I went with calcium deficiency and treated it as such top dressing with some plant food, epsom salt and garden lime. Seems to have done the trick...gave it a liquid treatment of plant food as well to get instant gratification...
Things are looking better

Sorry about your problem, I can't add much especially since I don't ken your nutrient program, but I would add that at this stage in flower, I'd get the RH below 50% to avoid any mold issues with your buds. Last time I got bud rot my RH got out of control due to getting sloppy while flushing, spiked up to 65% for a day, and that was all it needed, although I was also growing a super-dense bud strain, Immense Bulk, so that didn't help.
But good luck man, hope it doesn't get much worse, or that you can get across the finish line before it does.

still vegging last week i think and just started showing pistils. i normally drop the rH to below 50. my avg has been about 53-55 lately. It also spikes after watering for sure...

Well I was looking at your pics on page 1 which are flowering, must have misread your post.

Yea the original post was about another plant which is the dark Devil I have jarred now....
I also try to pay close attention to keeping my numbers in-line with the VPD chart. Today I’m on the border of going into the red zone but most of the time I stay in the green and yellow.
I’m flowering I’ll drop to 40-50% and 70-73F if I can control it...my grow space is pretty dialed in nicely...

Hmmm, not sure what a VDP chart is, but as a general rule I don't let my RH get above 50% just to avoid letting molds and fungus get started, but that's just me cuz I've had just about more issues with that than was ever caused by dryer conditions. Just a good preventative imo, but to each his/her own, eh ;?D

A good guide to follow. Plants have been very responsive and growth rates been good ever since I have tried to keep numbers in the green/yellow areas.
I try and use as many tools as possible...
