Self sustaining nuclear reactors occurred in the earth's crust 2 billion years ago, guess we can't out engineer them either? https://blogs.scientificamerican.com/guest-blog/natures-nuclear-reactors-the-2-billion-year-old-natural-fission-reactors-in-gabon-western-africa/

I'd back the co2 down considerably until you get everything else dialed in. Higher levels than our normal atmospheric level (If the lights are sufficient to support the increased metabolism) will dramatically exacerbate any other shortcoming or inadequacy in your grow setup, nutrient profile...
