looking fungal to me, try not to keep the leaves so wet. Might be some splash back from the medium when watering. pluck em, and monitor. soil regulates its own PH quite well. I would not be surprised if the roots are not getting enough oxygen as well from compacting or overwatering. Good Luck!

This could be Leaf Septoria this happens because of high temperatures and high humidity, best to remove all affected leaves and use neem oil on other leaves plants I don't know if this help but worth the try sorry cant help you more I never had this 😵
