Buy cal-mag in your grow store..and feed through the soil..it's the only way I give it if needed...

Yes but already giving magnesium won't adding more cause mag toxicity

Yes you can, well let me rephrase that, i did and it cleared up with in a week with leaves turning all green. The ones that are rusted never got better. I used light (1/2 teaspoon) per liter of epsom and soaked the plant at lights out. Worked great and plants loved it. They were in a hydro setup so watering should not effect it.
