From a fellow grower: Multiple fan leaves are curling along the edges, and look almost tube like, please advise.

[PharmerBob]

I could be wrong but in top right of pic looks like a body of water……

I’ve seen bugs do this, if I’m not mistaken it was broad mites

I’ll bet @Hellraiser lmows what causes this

[Hellraiser]

Yeah that is usually caused by excess heat, humidity, root problems (even bug related), or over-watering.
