Is this Ca deficiency?

Strains is Hindu Kush (not sure which seed bank, got them from a friend of a friend). 3rd or 4th week since hairs started to appear. Grown under 250w HPS,.

Soil was not the ideal choice maybe, got some organic soil for geraniums NPK 14 16 18....pretty strong, I know....only after I found a growshop not far from where I recently moved, but the plant already had several sets of leaves so I thought "go with the flow"

Overall, not a complete noob, I did several successful grows in the past using Bio Bizz Allmix, with no issues or deficiencies.....they were stealthy mini grows I must admit...

These brown splotches started to appear last week and seem to be spreading ....mostly on some middle and fan leaves.

Overall, plants look decent imo (sry for pic under HPS, it's just to give an overall look on their growth stage)- not sure if I should add some CalMag with my next waterings ( I water 2, maybe 3 times a week, the pots are 3 gallons more or less) I chose shallow ones ( the ones they use for potatoes :), due to height restrictions under the 250w HPS

Thanks in advance for your help!photo_2.jpgpht2.jpg

Looks not like cal deficiency I’ve seen looks more like moisture issues or over watering maybe to much humidity this is just my thoughts in the past in the bush or country I seen this in badly placed plants that lacked enough light an had to much water
