Calmag or Potassium deficiency

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.
