Beautiful ladies, hope you can keep them that way. That leaf looks like damage i've had off thrips in the past. Sorry can't advise on treatments, anything with garlic / chilli in though sounds like it will putthem off!
I’m not really seeing thrips (they are bigger buggers) but I’m going to take a better look tomorrow in the full sun. Thrips and white flys I can deal with in flower. Spider mites are a bit woolier. Thanks.
