Personally I can not see anything "strange" about any of the leaves, they look exactly how healthy cannabis leaves should look. Cannabis leaves come in all sorts of weird shapes and sizes and as long as they are nice and green, and the plant is growing well, there is no need to worry about tiny, little variations. No plant will ever have 100% perfect leaves, 100% of the time.

Hi Bud! I used exactly the same BioBizz nuts and soil in my first auto grown with RQS seeds and had the exact same issue. Exactly the same spots on the leaves... So I can say I'm 90% sure it is a Calmag issue. I solved it by adding CalMag from BioBizz to the feeding with their recommended dosage = issue solved. My water is pretty soft, around 50/70ppm so almost no Cal or Mag there, so pretty much expected. You are pretty early on the flowering stage so if you act now I don't think it will affect your yield. Good luck!
