If you're using calmag I don't see how you could be deficient in Calcium. Sounds like some sort of fungus to me. You can mix baking soda with water at 1 teaspoon to a half gallon and spray on the leaves, that will neutralize the pH on the surface of your leaves and prevent the fungus from growing. Apply a couple times over the course of a couple days and see if that helps. Happy Growing!

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…
