Browning on strawberry leaves

[Pnwgardens]

These strawberries have shot up in the past few weeks and they are producing leaves with browning around the edges and in some other spots.

Does anybody know what's causing it and how to treat it?

I don't know, but I had to click on a thread started by a Yoshi egg!

If I had to guess that’s a basic nitrogen deficiency.

I've filled all the pots with a few inches of compost, so hopefully that helps out.
