Going to start adding an extra mL of CalMag to see if this fixes the brown rust spots that just started popping up on the leaves
What’s your thoughts on this?
Make sure you check your calmag to see if there is N with it. Most will. Just adjust accordingly. The first few weeks of flower are where problems shine through and maybe adjust for next grow.
