I don't think it's a problem, but I was mainly just curious about something. Most of my newly emerging plants have curled up or malformed seed leaves that are brown on the ends like they've been burnt. They seem to look pretty good after a day or two, however. I soaked the seeds in 3% hydrogen peroxide for eight hours. This is the first time that I've soaked seeds in peroxide. Is this probably the cause? The seeds really germinated fast, though. Some broke through in 2 or 2 1/2 days.

Maybe too fast?

I have the same problem in some ones, but not in others and all of them received the same treatment.

I've thought the cause could lie on the germinating temp which was about 85 ºF. Actually the first germinating one, the 695 was removed one day before than the rest and received then one day less of that temp, and she has the most beautiful cotyledons you can desire in a seedling. She stayed 3 days at 85, then change to 75; while the rest passed 4 days at 85. All of them were removed as soon as a little of the seed was possible to be seen over the ground though.

We are using a high temp to germinate seeds in order to get the fastest start possible, but maybe a little slower one could be better for a correct young seedling development.

Is the soil very wet? house plants will get brown leaves on the tips of the leaves if the soil is way to wet. Over watering?

I had the same problem but I found that it was not the peroxide but being filed to far. If you file the green it will do that. Good luck.

I think you're right about the filing. Someone else mentioned that. Did you have any problems with the plants otherwise?

i have found that using a metal nail file works well for
me so far, as i have never filed seeds for germination until this year. if you file just deep enough until the color changes AGAIN, so you have a darker outside layer, which is the seed's outside color, then the light-colored
pith layer, i believe it is, then the darker lining of the seed, which is the last thing before actual seed-leaves
are exposed, you have gone far enough...just be careful to keep the file flat against the surface of the edge of the seed, and don't DIG into the seed with the edge of the file,
but go all the way around the edge except for the pointed tip. seeds seem to open up from the radicle (tip) end,
and i've had trouble because the rounded end remains intact
and necessitates manual seed coat removal...i'll be seeing the results of my first total filing efforts when my re-planted batch decides to come up! 'pal
