Leaves Brown spots

Hello everyone , two of my plant leaves are showing some brown spots as you can see in the image below. I have read it could be some cal deficiency, but since it’s my first grow, I’m not sure. Can some of you give me some inputs / help?

I stopped with cal-mag some weeks ago.



One more thing, looking at the pictures, how much time it should take to harvest? Two to three weeks maybe ? It’s currently starting the week 10 since sprout.

thanks in advance!

Anyone?

1. Overthinking “ one spot / blemish “
2. Nitro looks a bit high ( shiny leaf ) / minor claw
3. Narrow leaf pheno - throw calendar out window - gets done when it gets done.

lookin good keep going
