Bad Nutes?

Here we go again. I had this problem before in cocoa, So I went back to my old ways with the water table and it happened again. I'm tracing it down to possibly BAD NUTES. I had the batch #'s checked with G.H. and my stuff is not too old. I was using G.H 3 part with humic acid, cal mag, Big Bud powder and PH down to get it at about 6.3. All the additives were in trace amounts. I saw this happening then changed to PH adjusted water for a day and now I'm on Flora Nova. I don't know why I didn't love Flora Nova last time I tried it but I wanted to totally change the nutes. It was just changed so i won't have results for a few days. I'm expecting it to turn around as I can't figure any other reason for this than bad nutes. I've been running the same nutes for years with no probs.
My question is; Has anyone encountered the likes of this before? What's happening to me?

Forgot to mention a few things. It presents symptoms of Magnesium deficiency. The leafs get small spots like mites do then they grow to kill the leafs like the pics. Since I had magnesium availble to the plants I figure it's Lock out. DUh! But WHY? I DUNNO!
Thanks in advance
