Seedlings never get serrated leaves...

even after 12 days since they pushed through. What causes this and are they duds or am I being too impatient?
 
Ha. Those are the cotyledons. Every plant that grows from a seed will first produce these leaves (embryo leaves) and then the regular ones will start growing after that. They should grow on a second tier and grow in the opposite direction as the cotyledon leaves. Hope that helps.
 
I know those are the "embryonic" leaves. My concern is that its been over a week and still no sign of its first set of serrated leaves. All of my other seedlings got their first set of true leaves within 1-3 days of pushing through the soil. I want to know if I should continue to wait on this plant or just toss it?

Edit: Also, what causes this slow/stunted growth?
 
Even if this wasn't my first grow I wouldn't want to toss a plant unless absolutely necessary. I figure if it sprouts it deserves a chance. I guess no one knows the answer to my question but thanks anyway.
 
it's like this: some plants just grow weird. some seeds from the same pack take 5 days longer to pop than their siblings. however 12 days is WAY too long to not have a serrated leaf. the plant does not look stretched so it is unlikely to be a light issue. imo it's either the seed or the ph of the soil. in the pic the leaves are still green, so i'm leaning more toward this being the seed's fault. i wouldn't give up on it unless it dies though. i've had some killer bud come off plants that i had considered killing because of how they grew. check the ph of your soil to be sure. smaller containers can be more prone to soil contamination because of the small amount of soil. definately too soon to panic though.
 
I'm using FFOF and vegging under CFL's. I'll run to the hydro store and pick up a pH tester tomorrow. Thanks Total Head +rep.
 
I keep a strain that is and has been missing one finger on every leaf. If this plant doesn't produce any adults leaves at all this will be a new one for me. I once had a plant that had one finger leaves. The seeds in question were grown and produce in the Canadian climate.
 
When plants are crossbred and made to live in a climate that they are not mean't to be in, there will be genetic problems. I once had a potplant where all the adult leaves were smooth.
 
Took the advice to wait and see and this is where those seedlings are at:

You can see them trying to push their leaves thru. Poor retards :???:
 
Naw, these are 2 out of 9 that I have going at the moment. I could've tossed them but now I'm curious as to how long it'll take for them to develop, possibly even bud? They are both about 2 weeks old now so they should be done around this time next year :finger:
 
I've had this happen with other kinds of plants so take it for what it's worth... But every time it's happened, the seeds had either been stored for a long period of time or they were immature seeds. There is a period in healthy germination (right after the cotyledons open) where many plants can desiccate themselves and enter a period of dormancy to await better conditions if they germinated too early in the season. If you've ever germinated a bunch of seeds just for kicks and then neglected them without watering them, you'll notice how long the cotyledons will stay healthy and green looking - even after the rest of the stem/root has shriveled up - this is a practical example of the plant desiccating itself and entering dormancy to outlast bad conditions. With damaged/old/immature seeds they sometimes just don't ever leave this dormant stage or have a hard time doing so. I'd bet that's what is going on here, but it's pure conjecture.

You could try a low concentration of gibberellic acid or auxin on them to try and kick them into gear (normally this kicks a seedling out of dormancy and into self-production mode if the seeds/conditions are healthy). Many root stimulators contain auxins - might be worth a try.
