Problem with my plants leaves: Pics attached

[Betty2017]

Hi all,

Im having an on going issue with the fan leaves on my plant,

I've just started fkowering and in a week in to 12/12 but this isnt an issue thats just started its been going on throughout the veg stage (but not as bad as the huge spots ive just seen),

Ive read about a rust fungus but none if the colour comes of if I rub or scrape the leaf (or is that just a sometime thing,

It's my furst plant and im onlt growing one at the moment just to see how I get on,

I'ts an otherwise healthy plant, but could anyone give me any advice please Im getting a bit concerned,

Cheers

B

Are those small white round circles on your leaves? If so check for spider mites...

Calmag issue?

Experienced growers, ideas?
