Question about size of leaves

I am on day 26 from a seedling and I have leaves on my plants that span from my middle finger all the way past my wrist, and the leaves have been this big since day 20. Is this unusual? I don't see other plants with leaves this big in videos(this young). Just curious.

Happens with some indicas....

Some plants tend to grow big water leaves to bitch slap the grower in case it gets neglected. Be on alert at all times. As stated above, no big deal.
