Pepper Problems

I have several hot peppers that I have started from seed this year.  They currently look like this:

I am wondering is anyone knows what their issue might be.  To give a bit of history, they are potted in a sphagnum based potting mix, they had some fish bone meal added to the top layer of soil after planting, and were fertilized with some 2-4-4 fish/seaweed emulsion liquid fertilizer after transplanting into these bigger pots from their 3 inch ones.
