There are a million things you need to correct in order to even try to get them to grow, and most likely they won't reach near full potential, they didn't get proper nutrition,
UVB light, UVA light, temperatures, calcium supplementation, etc. during their baby/juvenile/subadult periods when growth occurs normally. But they can still have good lives if you properly house and feed them, though I guarantee that they also most likely are suffering from Metabolic Bone Disease and you need to focus on trying to remedy that as well.
Could you please post photos of both of them, their enclosure and lights, and then please answer the following questions so that we can tell you what changes need to be made and give any advice we can to you (it's a lot of questions, I know, but it is all information that we need to know in order to access what's going on:

LIGHTING:
1.)What brand, model, wattage, type (tube/regular lightbulb shape, or coil bulb) and size in inches (if a tube)
UVB light do each of them have? How far are their main basking spots from their UVB lights? If a long tube UVB, did you remove any plastic protective covers that came with the fixtures that were over the bulb? Are their UVB lights inside their enclosures, or are they sitting on top of a mesh or glass lid?

If so, are they bulbs that produce light, or Ceramic Heat Emitters that produce no light? How far away are their basking bulbs from their main basking spots?
3.)How many hours per day are your beardie's UVB and basking lights on?
TEMPERATURES:
1.)What are the 3 main temperatures in each of their enclosures (Hot Side, Cool Side, and Main Basking Spot)?
2.)What are you using to measure these temperatures (stick on thermometer, round gauge thermometer, digital thermometer with a probe on a wire, IR Temperature Gun, etc.)?
3.)If you are using a digital thermometer with a probe on a wire, are you allowing the probe to sit for 20-30 minutes in the testing spot before reading the temperature?
