...not really, it's a full soil amendment, not "targeted" to a micronute defc. but a shotgun blast of nutes,... Azomite is way too slow, the Micronic I don't know either, though it is nicely loaded and chelated,... Are you in Australia? If so, I can get a premier soil mate, @hecno , to chime in on sources for this... Check out his grows in Organic growing section, he's a total DIY soil builder and is crushing plant after plant with his home made goodness! He' knows the nute ropes better than anybody here for Down Under....
BTW, how close are your lights?

Thanks. Yeah lights may be a bit too close. Between 10-15". Been a balancing act with other plants in tent. I will move them up to be sure, especially with the recent stretching. Thanks for the advice. Much appreciated.

Pretty sure it is micronutes. The quirk and drity guide looks like Zinc and maybe an assortment of other micronutes issues. Looking forward to getting that cleaned up in my next grow. Hopefully micronutes defs explains why leaves end up burning off etc and isnt general nute burn. Starting new round in couple weeks. Woop!
