Tomato Seedling Problem

[Imperialboy]

So I started some seeds for fun. Some year(s) old seeds.
Now they seem to now be growing their second set of leaves and are reaching and curling upwards. I have grow lights on but I don't think they have ever affected them before.

They look ok. I really don't see any true leaves yet. It isn't unusual for the seed leaves to point up like that. Wait until they get true leaves and see what happens..

Yep, those look fine.

The embryonic Cotyledon leaf is what you are seeing. These will open up with warmth an light.


The first true leaves will grow out in a week or so.

Kk. So then I wait for two sets of true leaves. When I transplant I pinch off the first set.

They do that at night regardless of artificial light.


Do not pinch off the leaves when you pot up.

I would not pot up until the plants are so big that they are crowding each other. You should have problems keeping up with watering at that point.

[Imperialboy]

Alright. So then I still leave the first set of leaves above soil not pinched off

Kk. Thanks.
I was planning on potting up to 4" when they grow their 2nd set of true leaves
