Yea, the best thing to do is water the plant and then lift it up and judge the weight of it, you will notice a huge difference once it is dry, thats how i measure how dry the soil it. Just because its dry on top doesnt mean its dry underneath the soil. I would say if your plants arent drying out in 3-5days then they are not getting enough sun, and can lead to root rot, mold, etc.
Dont get me wrong, your plants look fine to me, the new growth looks alright, the plants look alittle loss for colour but that could have been the lack of sun from earlier on. I think she'll make a good comeback, just be patient with her, auto-bb is a finicky plant as is I find anyways.
