Possible deficiency on an auto

[Trichome_licker420]

One of my leaves on an auto has a little light brown dot on it. Not home for a photo. Could it possibly be calcium deficiency starting? Haven't used calmag on them yet. Fox farm happy frog soil.

It's hard to say without actually seeing the leaves that are affected
