Contrary to the normal peeps recommendations I would cull them. Start a new run. I think are wasting your time and effort and expenses. Autos have a short veg cycle before going in to flower. I'm surprised your girls are 28 days old TBH. If they switch to flowering as midgets you will be lucky to get a bowl full of medicine. I stopped one grow with 12 plants around day 25 because they were stunted. And totally glad I did. Within a week I found the new plants were just killing the old ones. Its super important to get your autos rocking right out of the gate.
What I would do is simplify your medium. Use coco with hydroton instead of mixing in peat with other stuff. Maybe some people mix things up but new growers shouldn't do that. It's for advanced growers. And use Tangs Easy with half strength nutes in the coco right away.
I would leave your current ones just to see what happens and in the mean time germ more in paper towels and drop in coco in either solo cups or right in the pots. You may find your new ones will quickly outgrow your old ones. Then you toss the old ones. That way you have a couple of irons in the fire. Seeds are cheap. your time is not.
Tangs Easy schedule is great. I did a couple of grows with it and no complaints.
