Magnesium lockout why?

Hi there OrganikTek, so with such a heavy light schedule the plant uses more Mg to regulate the photosynthesis , that's why you usually want something like extra calmag and some kind of additive to bring it to the plant. With these "high quality" genetics grown under perfect conditions in a lab, you will almost always find that they need more calmag than in nature. Maybe what you can do is add more calmag, or beneficial bacteria and hopefully they will make enough. Or reduce the light cycle which is the root cause of the problem. I know that is not a solution you want to hear, but i can show you an example where it solved the problem , and you can decide for yourself 😅 hope this helps ! 🚀
