First of all, it’s good to pot up if you can. Peppers tend to get used to their container and stop growing, which is sometimes very useful.
Yellowing leaves are generally a sign of nitrogen deficiency or low light. They are focusing their energy on their roots now that they have more room so they are ignoring leaf growth.
I’d prbabably start with adding some extra fertilizer. Half strength to start with. Assuming it is water soluble, they should bounce back quick. The leaves just need an extra boost once more roots are grown. If the potting soil doesn’t have fertilizer already, you want to add fertility about every 2 weeks. Once they go outside or into bigger pots you should add some organic dry fertilizer that will release slower.
I don’t know what kind of light you have or how strong, but you can get much closer to leaves. You can try closer to 3 inches away. If you want to try that, don’t worry too much if you get too much light and they start to brown on the edges, you can move it back up.
Other things – water every couple days, especially if you are bottom watering. Peppers are happy to get somewhat dry, but a week between watering is way too long. Now that they have more roots they can suck up much more water. And they need that to photosynthesis and build more chlorophyll.
The other option is that the new potting soil had the wrong pH or had a disease. Pretty rare but it can happen.
