Hello -- these seedlings are about 4 weeks old and are two that are showing some weird discoloration on their leaves as well as some bubbling and curling under. Crying

These are grown indoors (300W IR/UV/LED Vivosun light) and I'm using 100% fresh organic seedling mix from Gardener's Supply and has done very well - the other 14 seedlings are doing well.

Is this leaf burn? It doesn't look like the kind I am seeing online, so I thought D'Oh! go to the experts!! (Last night I raised the light another 6" from where it had been)

Leaf color change, lots of curling at the edges

Puckering/curling of the newer leaf next to the darker leaf

Another plant is showing similar symptoms but there isn't as much color change

One of its leaves is changing color -- lighter green and it looks like it has spots on it

Tagging @DraDiana in case she has any suggestions for this newbie Smiling

I'm no expert, but the curling of the new leaf makes me wonder about a plant virus...

Oh no!!!!! I thought it might be the light (too close) or maybe fertilizing too much (though I'm doing 1/2 strength).

These are all still indoors...

Someone on another forum mentioned pH....I'm not sure if that has anything to do with it. Confused Crying D'Oh!

@GenXNEGeorgia
My friend who used to run a wholesale nursery says to use only 1/4 strength fertilizer, or no fertilizer if the potting mix is pre-fertilized (like Miracle Gro). She says it looks like fertilizer burn.

Thank You! Hurray! Hurray!

I stopped fertilizing last week, pinched off the affected leaves and things look much better! I used 1/2 strength the first two times, so I will reduce even more. I also read Hibiscus don't like a lot of nitrogen, so I will try to find something a formula that's better suited to them.

I will breathe a sigh of release and stop worrying for now. The 16 babies are still doing well -- some are 5" tall with strong stems!

(Now if I could figure out why my basil isn't germinating..... Hilarious! )

Thank You! (again) I thought I might be cooking the seeds but maybe they like it Hilarious! so I'll go plug the germination mat back in Smiling

I tip my hat to you.

They look very good. I see some with "oakleaf" shaped leaves and the one on the farthest right in the upper picture looks like it has dark leaves like Starry Starry Night. Which cross is that one?

I think the one you're referring to is Mocha Moon x Midnight Marvel but the darkness is probably me trying to photograph the plants with the light on and then doing a bad job with the color correction D'Oh!

The 'oak leafed' ones tend to be Mocha Moon x Starry Starry Night

Thanks so much, James! This is my first time growing hibiscus (or anything successfully, really Hilarious! ) so I'm pretty thrilled. I hope they all stay healthy and bloom this year -- that would really be something else....

Jackie, I have grown them several times. At first it was just to add to collection. Then i had so many I grew them to give to family members. Enjoyed doing it. Will be starting a few again by request of a new Daughter in law. And do it with pleasure. I hope yours continue to progress well.

Thank you very much, James. I was fortunate that someone who crossed their hibiscuses shared a lo of seeds with me. I had surprising success germinating the seeds and they seem to be doing quite well. (I can't even get basil to germinate -- how backwards!)

If they all survive the next few months, I was considering gifting a couple as well. :-)
