Overall, the plant looks healthy.
I see a few leaves with deformities or slight decoloration around the edges of the leaves. But I am talking about maybe 1 or 2 leaves on a fan leave, and maybe 2 or 3 fan leaves in total.
Watering: This has been based on multiple factors. I have been poking my finger in the dirt, I use a dirt moisture meter and I pay attention to the overall look of the plant.
My latest watering was done Friday evening, with 7L (20% runoff).
I think I am going to switch to 12/12 this Wednesday. I will lower the net down 5cm if needed for guidence.
