Are these leggy? Buy fan or better lighting?

Took the lid off the propogator yesterday and started using the light, and already these look bigger and longer than they did yesterday!

I’m concerned though that they might be getting leggy.

What should I buy, better lights (that little LED strip doesn’t seem great) or a small USB fan for airflow?

Or are these ok for this growth stage?
