Something wrong?

Looking at your pictures the one that shows The top of your soil it appears to be damp so in my experience it is probably a little wet. If you’re new to gardening over watering is the most common issue. Probably the easiest way to fix it is to use the pick up the pot method ; if you pick it up and it’s light water it if it’s heavy or you ask yourself if it is heavy than it needs to wait another day. Still the method I use most of the time. Cannabis likes to dry the roots between waterings but not too long. You should water slowly, it should take a few minutes for each plant and water until you 10-20 percent runoff that way you should avoid any dry spots. Cal-mag if you don’t have any get some!!! It’s the most common problem with cannabis and one that’s easy to fix. Hope this helps.
