It looks like something called septoria to me 😔
I read in your diary these are outdoor plants and it's been wet and humid and those are ideal conditions sadly so go Google leaf septoria on cannabis and it will tell you the steps to try to treat it if you have more than one plant be very careful as the spots have spoors and you don't want it spread around
They suggest several things including removing every affected leaf and depending on how early you have caught it right upto spraying with neem oil but get on Google have a read there is alot of growers affected by this atm probably because of the weather pattern.
I hope you are able to treat your plants and nurse them back to health 🙏
