Bubbled leaves

That's the best I know how to describe it. Two or three leaves on a couple of my plants have developed these weird bumps on their leaves.

They appear healthy enough otherwise. The strains affected I believe are Agent Orange and Jack the Ripper, they are in a super soil mix made following this recipe: https://www.rollitup.org/subcools-old-school-organics/44686-subcools-super-soil.html

Let me know if anyone needs more info or pics.

Thanks
