So after just one dose of Cal-Mag my girl is already improving!!! The leaves with the brown spots are no longer yellow, they are green! As RT said, old leaves are old news, so the brown spots are here to stay, but I am pretty sure my girl is on the road to recovery.

I now have a better understanding of Cal-Mag deficiency, and have seen it in person. So although my plant was stressed, I now know what the symptoms are. Everything happens for a reason, and this is certainly a learning experience. Also, as I am still somewhat of a newbie to indoor growing, and I now have a much better understanding of pH and nutrient lock up.

Thanks again for your help Rusty!! I will keep everyone updated so they can learn from my post! I will post some recovery pics in a couple days.

I have 6 plants in Fox Farm soil, under a 400w hps, light at 12/12, circulation fan, temp stays between 72-76 degrees, humidity stays around 40%, watered with Nestle Pure H20 (which is supposed to be a pH of 5.5), and they are fed Tiger Bloom, and Big Bloom Fox Farm nutes every other watering (once/wk). All of the plants are big, green and healthy except for one, Wild Purple, which Rating: 5
