Buddy, I'm starting to feel like I'm just standing on my soap box preaching, I don't want to be that guy. But I do want to answer your questions, so, here I go again.
In terms of the plant - it does not care one iota if the nutrient X it is taking up was derived by a process that uses bacteria or one that uses man made chemistry. They are identical in terms of the plant. But if you are adding organic substances directly to the res (like nova) you HAVE to run a live res or you might as well dump your nova down the toilet. It's like adding
Great White to your sterile grow. Incompatible.
Yes the GH Flora 3 part is 100% inorganic, if you recall it works via chelation rather than microbe activity. BUTTTTT please don't confuse the fact that I still recommend a live system with non-organic nutes. There is more to the story.
Here is my advice my dude:
Lets get this plumbing and environment locked in how it needs to be to meet your goals.
Let's run a live res this time, you already have the orca.
Let's use the GH flora 3 part and
cal-mag only for one grow.
I'll bet, with a deeper understanding of what you are doing and why, you will find that this outperforms anything you have done before. Then, once you have the important stuff locked in your brain, when something shiny like koolbloom comes along, first thing you will do is read the label for ingredients and immediately know if this product will have no impact, some positive, or some negative impact on your grow. THATS when farming gets fun and you start winning POTM!
