What is this?

Some leafs have this rust spots what is causing that?
Another thing is that the breeder says 65 days from seed, but i highly doubt that they will be ready in time. At least more 2 weeks than breeders recomendation, What you guys think?
Currently Day 50 since germination
Autoflower gelato 33

My first guess would be either a Ca or Mg issue, but I’m not too sure.

As far as what the breeder says, take it with a grain of salt. Your plants will tell you when they’re done.

Get other opinions but I am thinking a combination of Mg and Ca deficiency.

I gave them CalMag last 2 feeding thinking it would be better but no signs of it. Even got a little worse. Don't know what is wrong
