I'm 90% sure this is Calcium deficiency as I've never actually added calimag or anything like that other than just the basic A and B nutrients so far. I was just hoping for a second opinion or confirmation

1) PICTURE OF PLANT *** VERY IMPORTANT *** CHECK
2) Growing indoor or outdoors - Indoor
3) Watering schedule - Once a day
4) Growing Medium - Soil
5) What stage of growth - about 4 weeks into flowering

Plant is an autoflower, its had a bit of a hard life to start off with but has been pretty good for the last 6 weeks up until a few days ago it started getting these brown spots.

Why I think it's Calcium going from all the great Leaf diagnosis websites like growweedeasy etc.

1. Brown spots on mainly the new leaves towards the tops of the plant,
2. Apart from these spots the rest of the leaf looks healthy.
3. It's not at the tips, however a few of the leafs that have a lot of brown spots the tips have curled and crinkling/dry.

I've just given the plant a ltr of water and .5ml of Calimag to see if it improves

Problems with new growth at the top would be one of the non-mobile nutrients.

Yeah I did the same thing with the google search, but only just mentioned the ones I new related to growing,
If you search Mobile Nutrients the list is the first result

Mobile nutrients are nitrogen in the form of nitrate, phosphorus (P) in the form of phosphate, potassium (K), magnesium (Mg), chlorine (Cl), zinc (Zn) and molybdene (Mo). Calcium (Ca), sulfur (S), iron (Fe), boron (B) and copper (Cu) are immobile.
