Too tall?

[Con420grow]

These two sprouted 4 days ago. They seem to be reaching even though I have my light turned down to 50%... does anybody have any ideas if this is okay?

They do that when they don't have enough light and are stretching up to it. Turn up the light or lower closer.

Ckbrew nailed the problem - low light. Your seedlings are stretching trying to get more light.
I'd turn up the light power, if your light has a dimmer switch. If no dimmer, you'll need to lower your light or raise the seedlings closer to it.
Best to do it now.
