My very first time starting seeds cabbage disease

[flowerbug]

I also don't see black spots, I do see holes in the leafs where something has nibbled on them. Could be slug damage, and as mentioned above they will most likely recover from it once outside.

if it is slug damage you can check around the edges of the containers and underneath them and in that area to see if you can find them hiding.

out in the garden if there is a slug problem i put old flat boards around the affected plants and then go out in the early morning and turn the boards over to see what they have collected - squish 'em or dispose and often within a few days/week it can remove most of the worst of the troublemakers.

oh, and the other thing that you can sometimes see with slugs is their trails on the leaves.

Madison mentioned black spots. Looking at the bottom three plants in the photo I see what are either black spots or tiny holes.

If it is slugs you can crush egg shells and put them right up next the base of your seedings. It tears up their bodies.
I think you need to do some studying and blow up your photos to see what the real culpret is. Here is a start for you.

They are in the garage and I do leave the garage door open sometimes so possibly! There are a lot of moths and flying ants and flies flying around the lights

Looks like pests. See if you can get a look at one.

i'd not worry, that's not enough damage to kill them and once they're planted out they'll likely outgrow any minor imperfections like that.

could be flea beetles or several other things but i'm not sure without being there.

you may have to net the plants to keep the cabbage moths off them (the small white butterflies that are often around).

Those holes are too big for flea beetles. I would thin cabbage loopers-try BT.

Those tiny black spots are probably the poop from whatever is eating them. Can you see any caterpillars on them? There are several different caterpillars that can attack cabbage, most of them are green but at least one is a dark gray. Some are the larva of moths, some of butterflies. The problem with that being damage from these is that the life cycle is that the moth or butterfly lays the eggs and it takes a few days for them to hatch. Are those sprouts old enough for caterpillars to have hatched and caused that damage? Still, that looks like caterpillar damage to me so check closely.

Flowerbug, aren't those holes really big for flea beetles? The flea beetle damage I'm used to is more like lace, not big holes like that.

Luckily I haven't had that much experience with slugs. For those that have, could that be slug damage. If those tiny black spots are poop I think it is too small to be from slugs. I'd think the inside of the garage would be too dry for slugs anyway.

I can't come up with any flying insect that would make holes that look like that and have poop that small.

Madison, I can't remember where you said you are, if you did, and I'm too lazy to go check. Where are you, that might eliminate some things. If you modify your profile to show general location that information will always be available.

There are no bugs on or around them save for a few flies, mosquitos and gnats. There are a few moths as well but we kill all of those when we see them so there haven't been any very long and there were never any eggs present on the plants. I would think these seedlings are not old enough to have hatched and caused so much damage. I am located in the Texas panhandle.

What is BT?

I am pretty certain it isn't slugs.

They are black spots. I can wipe or dust the black spots off of the leaves.

I have done hours of research trying to find this culprit. I know about the eggshells but it definitely isn't slugs.
