...first, it's not hard to get rid of mites, but while your girls are unhealthy is another question...
It’s hard to tell from the photos, but the 1st pic looks female, the 3rd looks male and I can’t find any preflowers on the rest.
Don’t water everyday — the soil needs time to dry out between waterings. It’s not your fault, as this is something that’s beaten into our heads as school children about plants loving lots of water. I’ve got 2-week old seedlings that I’ve watered once sign they germinated. Most of my plants get watered once a week. Too much water drowns the roots and stunts the plant.
I’ve heard that spraying with soap and water works for spider mites, or even flipping the plant upside down and dunking the entire thing in a bucket of soap and water. However, I haven’t tried these things myself. I have sprayed with a biopesticide containing pyrethrin and that seemed to work for a while, though it wouldn’t use that when the plant is flowering. Having a fan on the plants helps prevent spider mites, as they love still air. Definitely take your plant out and clean your tent. Search around on the site for preferred mix (hydrogen peroxide or whatever).
