Rusting spots or deficiency?

[Dylbecks]

Been seeing these spots popping up all over the place in my tents, from what I've gathered from others in my network they tell me it's probably CalMag deficiency, however, I am on the closing phase (hopefully) of getting rid of spider mites I had 10 days ago. Leads me to think it could be rust but no one I know has personally dealt with it, so here I am asking for your opinions.

I've posted a picture of the mites under a microscope in case that is a useful detail

I had some rust a few weeks ago...upped my feeding dose and hit em with Epsom salts and dolomite lime 2-3 waterings in a row and it stopped

When you Google n read abt rust it opens all kinds of cans of worms n possibilities...says it contagious and this n that...had me worried to death by the time I was finished it's like googling "heart palpations" or "breathing difficulties"...between your own mind and Google you will have convinced yourself your dying by the end of your research...ha

Or maybe that's just me

I know that feeling lol I had to take a food chemistry class in college and I know how hard it can be to get rid of some fungal infections from that. Probably will just stunt the growth at wors

After how hard it was to get rid of the spider mites I'd like to just chill for a bit on my spare time XD. Still spraying them with lost coast every 3 days at 2tbsp/gal to be safe

I increased CalMag to 5ml/gal and it hasn't been giving me issues since

So I would need to use calmag never had issues with first organic grow.
Only difference this time is I added the fish,blood and bone meal so I'm wondering if this has caused issue.
