Hello JoshFirstly the rose hairs need more floor space than height,they also enjoy a drier substrate. As for the thriving,it could be the containers,since if it was the substrate all 4 should have an issue. Now something else,rosea are known to stay without food for extended periods but if these are still small that shouldn't come in to play.Something else you have to consider,the two faster growing rate ones could be males who will eat better since they grow for one thing mating. Their life expectancy is way shorter than their female counterparts,so growth will look the opposite compared to the female of the same genus.If your specimens don't have shrunken abdomens no need to worry, as long as they are eating and consuming water all should be okay. I would just look at getting a type of enclosure later that suites terrestrial specimens,but I'm guessing they are small that which you are using should be fine. May I suggest filling up each container with 2/3 of sub,so if they want they can burrow.
