My opinion..... I do not know the problem but I'd get them into final containers, whatever size you wanted. They look oversized (rootbound) for your containers which look 1-2 quart. Put them in your final potting soil in a larger container. Check pH of medium.
There is something nutrient-wise going on they do not like. Give them a fresh environment of a larger container with some new potting soil and no nutes. Trim all leaves that are 50% yellow or affected.
Just my opinion.
