If I remember right, Brussels sprouts, cauliflower, and broccoli seedlings all look pretty similar. I grew some last spring, and if I hadn't labeled them, I don't know if I could have told them apart. Did quite a bit of searching on the Net. This is the only picture I've found so far of just sprouted Brussels sprouts. Here is a link that might be useful: Young Brussels sprouts, etc.

Gardengals pictures look great- Here in Woodstock, Ga my newest seedlings are still very rough looking- the leaves have not seperated and are pale as I just pulled the leaf cover off them,Also they are lanky from trying to reach throught the leaves. When in doubt give them time! Best regards, Diamondcil

BTW I have a UV light (the kind you use for reptiles) and a heat lamp that also produces full-spectrum on the plants for a few hours a day in addition to the sun through the terrace (which is 4-5 hours now). I have seen some small insects, really small, like gnats. I wonder if that is the problem? I watered the plants with a garlic mix (boiled garlic in water, essentially). That, I figured would take care of most things. But I am still curious what this is and if it is thrips or something. (I did hit them with a teensy bit of insecticide on the soil, just in case).

My oregano was started from seeds the beginning of April and now have an inch or two stems of tiny green leaves, similar to thyme. The thyme leaves are on 3 inch stems though, and were started the same time. I also have rosemary started from seed and these too have a few small leaves. Just planted all of these, along with basil, shallots, asparagus, and tarragon, in my garden. There are a few varieties of oregano, with smaller round leaves, as well as larger oval pointed shaped leaves like the photo above.
