"Rust" on some leaves

Thank you, you are great help I ll check it out.
I saw some where something about wind burn and it looked similar to my problem. I ll post a link, if I will find it again.

Here it is:
I don't know how to post a link thru my phone. The lunk icon is grey and I can't click on it.

I also read some comments where were saying that the mostly indica strains needs much more calcium than sativas. And I noticed here in my example that the only ICE and Domina(indicas) had this signs of brown spots. Other my less pure indicas(Cookies, Gorilla, Skunk, Critical and Unlimited), does not showing this signs fir now.
And as I remember from my previous grow, was similar situation.

Can anyone confirm that indica-led-calcium deficiency relation?

Alot of the main problems look a like just got to read into it a bit further and you will find more similarities to your problem that's what I do atleast then you can pin point better. And what I have learned is make sure 100 percent you know which problem it is before you try and fix it because I thought I had problem a so tried to fix it and now I have problem b bc what I used to fix a just led to another problem bc it wasnt correct I dunno if I said that in a way u can understand hopefully I did.

Yes, I know what you are trying to tell me. I still think that the problem is calcium or mag defficiency. Wind was only a thing which cames nearby...
I read as many articles as I can, but this leaf indicators could be so similar to each other.
And every time I look at my plant I can see other sign... I need a break, lol

Did you do any foliar sprays?

Definitly a calcium deficiency just typed that in on the growweedeasy page and pics with thos exact drown spots came up.
