Gus Scout Cookies

Looks overfeed vs under to me.

calcium and magnesium are two elements and have slightly different symptoms. I bet you are too high in K which is also locking some other things out. After i do some sloppy quick math of weighted average of what you have been feeding the last few weeks. It's getting enough N (possibly a skosh too much) so that means potassium must be sky-high given the rough weighted average of npk. And it got worse the last week at a faster pace than before, which if i read teh diary right is also coinciding with a bump to "bloom" which only futher gives confidence it's too much K. doubling up on micros with some in the "micro" and some in the "cali-mag extra product" too. More is not necessarily better in this regard. remember it's not foie gras... there are upper and lower limits. you want the goldielocks zone of "just right" .. and that varies by location - temps, rh, co2, lights etc.

Pic 3 looks like burning from excessive nitrogen or fertilizer salts, rest of the pictures look a bit like potassium deficiency. It takes 2 weeks or so for any improvements to become seen in the leaves after any remedial treatments. As this plant is so close to harvest, I doubt there is anything you can do to make things look better/fix things before harvest maturity. Had you asked ths question 2 weeks ago, when these symptoms probably first appeared, there may have been a chance to improve things slightly. Anyway, at this late stage, just keep going and she should be ok, but even upping the K now, won't have any time to help.
