Hi!
It looks to me like you may have a possible mite/insect problem with some, if not all of them. Have you inspected them with magnification for pests?

i am by no means a "petiolaris" expert, but i have successfully brought my petiolaris plants out of dormancy, and have been growing them for almost 2 years now...and from what i can tell, it does look like your plants are entering dormancy if not in dormancy already. my advice would be, provide some means to keep the humidity high, keep the pots dry as you already have, and keep your temperatures as high as possible (~35F), water every 9-12 days using the tray method filling up to .5 to 1 cm of water, or as much as the pot can absorb within a few hours....growth will start to increase as the plant breaks out of dormancy---during this time you can increase the watering frequency until the plant grows normally; at this time you can water log them if you wish. cheers.
