Yellow Leaves at Growth Stem

[Spartanburg123]

Has anyone observed yellowing in the young leaves right at the growth stem? They gradually darken to green as the leaf matures, but this has puzzled me. This is not the first time I've noticed this. These two plants are the only ones doing this, and they are in pots right next to each other. Thanks!

The plant on the left is DLH from my original saved seed, and the one on the right is a PL curiosity from Dutch's saved DLH seeds.

Something similar happened to a few of my plants last year, and I think the consensus was that it was due to overwatering and it's effect on root uptake.

This type of yellowing is called Chlorosis. Generally caused by nutrient deficiency either due to actual deficiency in the soil or caused by ph issues or overwet conditions that limit the plant's ability to take up nutrients.
Since they are in pots, the more likely issue is need for fertilizer. A good balanced one with micronutrients such as iron and magnesium should fix it.

Maybe pull some of your mulch away from the stems a bit. Mulch is great for keeping weeds down and holding moisture but i keep it away from touching stems. Especially such a heavy mulch.

Epsom salt and dilute good fert food will correct but let them dry out a bit first.
I'm pretty stingy with food when that young unless i see something like that....

They will recover and look very healthy otherwise.

Take the airbrush away from your garden gnomes.


And remove the mulch - at least for a while. You can't judge the saturation of the soil if you can't see it. Are you perchance watering "on a schedule"?

bwahaha Forcier! I give them a sprinkle every two days. Thanks to all of you! I'll get out the ferts and Epsom.

Yes, chlorosis. Check out this picture or chlorosis caused by iron deficiency

If the problem is over-wet or high pH then adding ferts won't help.

Great link! Thanks!

Out of dozens of plants, something like that happened to my lone Black Cherry. But now it has gone away. At first I thought it looked like herbicide damage !!! But how ? from what ?

BTW: Darin, what kind of mulch is that you are using ?!

[KarenO]

Neither disease or herbicide damage can be corrected. Deficiency can be corrected.

I agree, that's classic symptoms of an iron deficiency.

[Antipodean]

Yes, iron deficiency!

Usually caused by the pH being too high (alkaline)......not due to low iron levels.

Could be caused by your tap water being alkaline, could add a bit of vinegar to your watering can.

I would not rush to make any adjustment on a seedling that will be planted outdoors soon. It will probably correct itself and you may kill it with kindness trying to make adjustments.
