is this what the plants look like?

I think you can safely rule out the plants with multiple sets of little round leaves; those aren't cannabis. The one(s) with the serrated leaves, I'd let them go a little longer, but even those are looking doubtful at this point.

hotnrthernguy, i saw one of those plants your growing today. it was in the same pot that my marijuana plant is growing in. lol, funny coincidence.

Couple tips:
The placement of your light is very bad. It will cause the seedling to stretch sideways. You need lighting coming from above, CFLs almost touching the tops of the seedlings.

You buried the seedlings too deep when you transplanted. The leaves should not be touching the soil=potential for rot.

Peat moss is too acidic. Unless you treated it with lime already and know the pH is correct, stay away from the stuff.

And lastly, those weren't cannabis when they sprouted and they still aren't.

Every one has the wrong cotyledon formation. Some are too oblong, and the seedling you have with little round cotyledons, those are on petioles, whereas cannabis cotyledons have no visible stems. The plant with the serrated edges STILL looks like a hollyhock to me- was the seed sort of flattened looking?

Anyway this is just getting silly. Look at Sandman's pic. The cotyledons should be round and plump, on no stems. The first adult leaves should be long, pointed, serrated, and single, on short petioles. The second adult leaves can be either single or triple, depending on if your plant is healthy. The next set will be 5.

But keep on growing the tagalong seeds that came in your soil if you feel like it. I'm not laughing, promise. This is just getting kind of sad.

You delivery bad news ....like a heat-seeking missile. That's the way I like my bad news.
