Yes, to me they look like normal pepper plants. Lots of times plants slow growth after a transplant but yours look like they are suffering no ill effects. Give them time.

When I planted out my peppers in compost/ peat/vermiculte, they
turned yellowish. I also use some fish fertilizer like you did. They are
much better now. Like esox said you have to give them more time to correct
themselves.

Patience is a virtue growing chiles.

They look like they have more water than they would like, but, that's early season for you. Did you remove the peat pots or plant them like the instructions say? I always remove them. I just think they do better that way.

I did plant them in the peat pots. I may try without the next time, or at least score them to help them split and break down quicker.

The jalapenos and bananas are starting to perk up, the habaneros look worse. They're starting to get brown spots on the leaves.

Yep, looks like crisis time for those poor little Habbys. Sorry, I cannot help you diagnose the problem though.

i would pull them out of the gound and pot them up in some fresh well draining soil and keep a close eye on them. they might be too wet. but that is just me and i am really new to gardening. but just my .02C

What sort of well draining soil should I put them in if I pull 'em up?

well, half mine are in my own concoction with bark/sunshine growers mix#4/EB stone cactus mix. 5-1-1 but other plants i have stricly in the growers mix and it drains/dries out pretty darn quick.
