Whats a good thing to use for trace nutrients? and is Grow Big, Tiger Bloom, SuperThrive and Monster Bloom fine?
Grow Big should have plenty of the micro/trace nutrients your looking for. So you'll be good there. Then the super thrive is a growth hormone and B vitamin. You should just get rid of that Tiger Bloom, because the Monster Bloom is gonna have that part of things already handled. If you keep the tiger bloom, I would add it at half strength, just to be safe.
The only thing I would add to your mix is a calcium magnesium supplement. Once you get to about the 3rd-5th week of flowering... plants really need that extra magnesium and calcium to keep things bulking up and preventing your leaves from yellowing too early in flowering. Plus cannabis plants just love calcium and magnesium. I would recommend General Organics CaMag+. Its some good stuff. And it works as a beneficial bacteria feed.
Oh... and maybe some microlife. Beneficial bacteria and organisims help to keep your root zone nice, clean and healthy. If you have happy roots, your gonna have a happy plant. So maybe some Great White or Sea Green ... or maybe that new stuff Orca.
I can keep going if you want?? lol
