It's just that bark is not a great medium for growing you plants. It's very acidic and give you a very low ph. Also roots prefer to grow around the bark which slows root growth, and plant growth even more. But don't worry, cause even badly stunted plants can apparently fully catch up after being re-potted. I'd let those babies grow until you can re-pot them and put them a good quality compost and perlite.
