Calcium deficiency or what?

[shadycon]

Early Frost, 14 wks. old in soil. This plant has had light makings on leaves since veg. Now I'm getting dark brown splotches I have been adding Cal-mag to water once a week for two weeks.No change so far. Should I be concerned? Started flowering a month ago.

Did you check the pH yet? I had a similar problem on my plants and discovered it was because the pH was too low.

I'm going easy on nutes once a week and water when pot is light.

I use ground water and it is within range
