Hi, I am still a fresh newbie here, please guide me to care for my baby.

Few days ago I tried to germinate my last and only Delahaze seed with a mixture of H2O2 3% and water, and it is a great success.

On 29 April, I put the sprout inside the soil mix with perlite. And on 30th the cotyledon broke out from the seed shell, but the membrane stuck so the cotyledon cannot open, so I carefully remove the membrane.

Now it is 2nd of may and the cotyledon does not open fully like the image below and I can see the first set of leaf in between the cotyledon

What should I do so the cotyledon will open its leaf fully??

Thank you :)

WAIT
 
Part of the membrane inside the seed shell is still attached to the cotyledons.
Mist it with water and it will soften so you can easily but gently remove it.
I do it all the time without issue.

Thanks for replying MickFoster!

Yes I have successfully remove it yesterday by lightly watering the sticky membrane.

As the membrane removed I finally can see slight gap between the leaf

Is there any problem you can detect from the photo?

How about the colour of the stem is it normal?
