Could this be a calcium deficiency?

[KBgrows420]

Hey guys came down to water the plants today and noticed a couple of my leaves had these brown spots and a little bit of yellowing with it could this be a calcium deficiency? If so how do I fix this before it spreads?

Pick up some cal/mag and use it as directed.

What are you doing for Ca, Mg and P? Grow details and full plant pics would also be helpful.

I use Advanced Nutrients' Cal-Mag Xtra. I grow in an RDWC set up and basically use this feeding schedule adjusted with the necessary additives to work with hydro.

Can you take the pics under natural white light? How often do you feed vs. plain water? How frequently do you use the Cal Mag?
