If I see brown rust spots like the 2nd pic I know I need some Epsom salt for magnesium. if the leaves start turning a lighter green like the first pic it’s time to add more nitrogen and if you start seeing that weird yellowish green like the 2nd pic add Calcium or calmag

I'm having the same issue with Triangle Kush, at the moment. I know the soil-less mix has enough nutrients in it....but, I screwed up and did not pH my water/fertilizer (which was acidic) last time and so I created a lockout. Instead of jumping all over the Cal-Mag (like I've done many times in the past), I will adjust the pH of my next watering to be slightly higher-than-normal in order to correct the problem. Once the pH is corrected, the plants will be able to absorb what is already there for them.

Don't over correct, just use normal PH nutrient solution.
